To solve the equation -7x = 42, we can divide both sides by -7 to isolate x:
(-7x)/(-7) = 42/(-7)
x = -6
To check our answer, we substitute x = -6 back into the original equation:
-7(-6) = 42
42 = 42
Since both sides of the equation are equal, our solution is correct. Therefore, x = -6.
(-7x)/(-7) = 42/(-7)
x = -6
To check our answer, we substitute x = -6 back into the original equation:
-7(-6) = 42
42 = 42
Since both sides of the equation are equal, our solution is correct. Therefore, x = -6.

To solve the equation 78 = 1.5x, we can divide both sides by 1.5 to isolate x:
78 / 1.5 = 1.5x / 1.5
52 = x
To check our answer, we substitute x = 52 back into the original equation:
78 = 1.5(52)
78 = 78
Since both sides of the equation are equal, our solution is correct. Therefore, x = 52.
78 / 1.5 = 1.5x / 1.5
52 = x
To check our answer, we substitute x = 52 back into the original equation:
78 = 1.5(52)
78 = 78
Since both sides of the equation are equal, our solution is correct. Therefore, x = 52.

x = -50
To check our answer, we substitute x = -50 back into the original equation:
(-50)/5 = -10
-10 = -10
Since both sides of the equation are equal, our solution is correct. Therefore, x = -50.
(x/5) * 5 = (-10) * 5
x = -50
To check our answer, we substitute x = -50 back into the original equation:
(-50)/5 = -10
-10 = -10
Since both sides of the equation are equal, our solution is correct. Therefore, x = -50.

5/3(9) = 15
15 = 15
Since both sides of the equation are equal, our solution is correct. Therefore, m = 9.
(5/3m) * 3 = 15 * 3
5m = 45
Next, we divide both sides of the equation by 5 to isolate m:
5m/5 = 45/5
m = 9
To check our answer, we substitute m = 9 back into the original equation:
5/3(9) = 15
15 = 15
Since both sides of the equation are equal, our solution is correct. Therefore, m = 9.

To solve the equation 7/4m = 1/4, we can start by multiplying both sides of the equation by 4 to get rid of the fraction:
(7/4m) * 4 = (1/4) * 4
7m = 1
Next, we divide both sides of the equation by 7 to isolate m:
7m/7 = 1/7
m = 1/7
To check our answer, we substitute m = 1/7 back into the original equation:
7/4(1/7) = 1/4
1/4 = 1/4
Since both sides of the equation are equal, our solution is correct. Therefore, m = 1/7.
(7/4m) * 4 = (1/4) * 4
7m = 1
Next, we divide both sides of the equation by 7 to isolate m:
7m/7 = 1/7
m = 1/7
To check our answer, we substitute m = 1/7 back into the original equation:
7/4(1/7) = 1/4
1/4 = 1/4
Since both sides of the equation are equal, our solution is correct. Therefore, m = 1/7.

To solve the equation -22 = 2 + 4x, we can start by subtracting 2 from both sides of the equation:
-22 - 2 = 2 + 4x - 2
-24 = 4x
Next, we divide both sides of the equation by 4 to isolate x:
(-24)/4 = (4x)/4
-6 = x
To check our answer, we substitute x = -6 back into the original equation:
-22 = 2 + 4(-6)
-22 = 2 - 24
-22 = -22
Since both sides of the equation are equal, our solution is correct. Therefore, x = -6.
-22 - 2 = 2 + 4x - 2
-24 = 4x
Next, we divide both sides of the equation by 4 to isolate x:
(-24)/4 = (4x)/4
-6 = x
To check our answer, we substitute x = -6 back into the original equation:
-22 = 2 + 4(-6)
-22 = 2 - 24
-22 = -22
Since both sides of the equation are equal, our solution is correct. Therefore, x = -6.

To find out how many boxes of books the delivery person can bring up at one time, we need to subtract the weight of the delivery person from the maximum capacity of the elevator and then divide the result by the weight of each box.
Maximum capacity of the elevator - Weight of the delivery person = Maximum weight for the boxes
920 lb - 180 lb = 740 lb
Now, we need to divide the maximum weight for the boxes by the weight of each box to find out how many boxes can be brought up:
740 lb / 50 lb = 14.8
Since we cannot have a fraction of a box, the delivery person can bring up a maximum of 14 boxes of books at one time.
The delivery person can bring up 14 boxes of books.
Maximum capacity of the elevator - Weight of the delivery person = Maximum weight for the boxes
920 lb - 180 lb = 740 lb
Now, we need to divide the maximum weight for the boxes by the weight of each box to find out how many boxes can be brought up:
740 lb / 50 lb = 14.8
Since we cannot have a fraction of a box, the delivery person can bring up a maximum of 14 boxes of books at one time.

To solve the equation k - 3/5 = 11, we can start by adding 3/5 to both sides of the equation:
k - 3/5 + 3/5 = 11 + 3/5
k = 11 + 3/5
To add 11 + 3/5, we need a common denominator. The common denominator between 5 and 1 is 5. Thus, we can rewrite 11 as 11/1:
k = 11/1 + 3/5
To add these fractions, we need a common denominator of 5:
k = (11/1)*5/5 + 3/5
k = 55/5 + 3/5
k = 58/5
To check our answer, we substitute k = 58/5 back into the original equation:
(58/5) - 3/5 = 11
55/5 = 11
11 = 11
Since both sides of the equation are equal, our solution is correct. Therefore, k = 58/5.
k - 3/5 + 3/5 = 11 + 3/5
k = 11 + 3/5
To add 11 + 3/5, we need a common denominator. The common denominator between 5 and 1 is 5. Thus, we can rewrite 11 as 11/1:
k = 11/1 + 3/5
To add these fractions, we need a common denominator of 5:
k = (11/1)*5/5 + 3/5
k = 55/5 + 3/5
k = 58/5
To check our answer, we substitute k = 58/5 back into the original equation:
(58/5) - 3/5 = 11
55/5 = 11
11 = 11
Since both sides of the equation are equal, our solution is correct. Therefore, k = 58/5.

Apologies for the mistake. Let's solve the equation correctly.
To solve the equation k - 3/5 = 11, we can add 3/5 to both sides of the equation to isolate k:
k - 3/5 + 3/5 = 11 + 3/5
k = 11 + 3/5
To add the fractions, we need a common denominator of 5:
k = 11 + (3/5)
k = (11 * 5/5) + (3/5)
k = 55/5 + 3/5
k = 58/5
Therefore, the solution to the equation is k = 58/5.
To solve the equation k - 3/5 = 11, we can add 3/5 to both sides of the equation to isolate k:
k - 3/5 + 3/5 = 11 + 3/5
k = 11 + 3/5
To add the fractions, we need a common denominator of 5:
k = 11 + (3/5)
k = (11 * 5/5) + (3/5)
k = 55/5 + 3/5
k = 58/5
Therefore, the solution to the equation is k = 58/5.
