What is the solution of the equation 2(x + 9) = 16 when solving for x

Answer 1

To solve the equation 2(x + 9) = 16, we will begin by simplifying the expression on the left side of the equation:

2(x + 9) = 16
2x + 18 = 16

Next, we want to isolate the variable x on one side of the equation. To do this, we subtract 18 from both sides:

2x + 18 - 18 = 16 - 18
2x = -2

Finally, to solve for x, we divide both sides of the equation by 2:

(2x)/2 = (-2)/2
x = -1

Therefore, the solution to the equation 2(x + 9) = 16 when solving for x is x = -1.

Answer 2

What is the solution of the equation 8(x − 10) = 56 when solving for x ?

Answer 3

To solve the equation 8(x − 10) = 56, we will begin by simplifying the expression on the left side of the equation:

8(x − 10) = 56
8x - 80 = 56

Next, we want to isolate the variable x on one side of the equation. To do this, we add 80 to both sides:

8x - 80 + 80 = 56 + 80
8x = 136

Finally, to solve for x, we divide both sides of the equation by 8:

(8x)/8 = (136)/8
x = 17

Therefore, the solution to the equation 8(x − 10) = 56 when solving for x is x = 17.

Answer 4

What is the solution of the equation 10(z − 1) = 50 when solving for z ?

Answer 5

To solve the equation 10(z − 1) = 50, we will begin by simplifying the expression on the left side of the equation:

10(z − 1) = 50
10z - 10 = 50

Next, we want to isolate the variable z on one side of the equation. To do this, we add 10 to both sides:

10z - 10 + 10 = 50 + 10
10z = 60

Finally, to solve for z, we divide both sides of the equation by 10:

(10z)/10 = (60)/10
z = 6

Therefore, the solution to the equation 10(z − 1) = 50 when solving for z is z = 6.

Answer 6

What is the solution to the equation 5(x − 10) = 65 when solving for x ?(1 point)

Answer 7

To solve the equation 5(x - 10) = 65 when solving for x, we will begin by simplifying the expression on the left side of the equation:

5(x - 10) = 65
5x - 50 = 65

Next, we want to isolate the variable x on one side of the equation. To do this, we add 50 to both sides:

5x - 50 + 50 = 65 + 50
5x = 115

Finally, to solve for x, we divide both sides of the equation by 5:

(5x)/5 = (115)/5
x = 23

Therefore, the solution to the equation 5(x - 10) = 65 when solving for x is x = 23.

Answer 8

What is the solution to the equation −4(x − 8) =−32 when solving for x ?(1 point)

Answer 9

To solve the equation -4(x - 8) = -32 when solving for x, we will begin by simplifying the expression on the left side of the equation:

-4(x - 8) = -32
-4x + 32 = -32

Next, we want to isolate the variable x on one side of the equation. To do this, we subtract 32 from both sides:

-4x + 32 - 32 = -32 - 32
-4x = -64

Finally, to solve for x, we divide both sides of the equation by -4:

(-4x)/-4 = (-64)/-4
x = 16

Therefore, the solution to the equation -4(x - 8) = -32 when solving for x is x = 16.

Answer 18

What is the solution of the equation −4(z + 12) = 36 when solving for z ? (1 point) Responses −6 negative 6 24 24 −21 negative 21 21

Answer 19

To solve the equation -4(z + 12) = 36 when solving for z, we will start by simplifying the equation:

-4(z + 12) = 36
-4z - 48 = 36

Next, we want to isolate the variable z on one side of the equation. To do this, we add 48 to both sides:

-4z - 48 + 48 = 36 + 48
-4z = 84

Finally, to solve for z, we divide both sides of the equation by -4:

(-4z)/(-4) = 84/(-4)
z = -21

Therefore, the solution to the equation -4(z + 12) = 36 when solving for z is z = -21.
