Let's call the number "x".
The difference of a number and 7 is x - 7.
Four times the difference of a number and 7 is 4(x - 7).
We are told that this expression is equal to 12, so we can set up the equation:
4(x - 7) = 12
Now, let's solve for x:
4x - 28 = 12
Adding 28 to both sides:
4x = 40
Dividing both sides by 4:
x = 10
Therefore, the number is 10.

To solve the equation −7x + 40 = −37, let's isolate x on one side:
We'll start by subtracting 40 from both sides of the equation:
−7x + 40 - 40 = −37 - 40
This simplifies to:
−7x = −77
Next, we'll divide both sides of the equation by -7 to solve for x:
−7x / -7 = −77 / -7
This gives us:
x = 11
Therefore, x = 11 is the solution to the equation −7x + 40 = −37.
We'll start by subtracting 40 from both sides of the equation:
−7x + 40 - 40 = −37 - 40
This simplifies to:
−7x = −77
Next, we'll divide both sides of the equation by -7 to solve for x:
−7x / -7 = −77 / -7
This gives us:
x = 11
Therefore, x = 11 is the solution to the equation −7x + 40 = −37.

To solve the equation m/8 - 4 = -12, let's isolate m on one side:
First, we'll add 4 to both sides of the equation to eliminate the -4:
m/8 - 4 + 4 = -12 + 4
This simplifies to:
m/8 = -8
Next, we'll multiply both sides of the equation by 8 to solve for m:
8 * (m/8) = -8 * 8
This gives us:
m = -64
Therefore, m = -64 is the solution to the equation m/8 - 4 = -12.
First, we'll add 4 to both sides of the equation to eliminate the -4:
m/8 - 4 + 4 = -12 + 4
This simplifies to:
m/8 = -8
Next, we'll multiply both sides of the equation by 8 to solve for m:
8 * (m/8) = -8 * 8
This gives us:
m = -64
Therefore, m = -64 is the solution to the equation m/8 - 4 = -12.

To solve for x in the equation 25(10x+15) = 26, we can start by distributing the 25 to the terms within the parentheses:
25 * 10x + 25 * 15 = 26
This simplifies to:
250x + 375 = 26
Next, we subtract 375 from both sides of the equation to isolate the term with x:
250x + 375 - 375 = 26 - 375
This gives us:
250x = -349
Finally, we divide both sides of the equation by 250 to solve for x:
250x / 250 = -349 / 250
This results in:
x = -1.396
Therefore, the solution to the equation 25(10x+15) = 26 is x = -1.396.
25 * 10x + 25 * 15 = 26
This simplifies to:
250x + 375 = 26
Next, we subtract 375 from both sides of the equation to isolate the term with x:
250x + 375 - 375 = 26 - 375
This gives us:
250x = -349
Finally, we divide both sides of the equation by 250 to solve for x:
250x / 250 = -349 / 250
This results in:
x = -1.396
Therefore, the solution to the equation 25(10x+15) = 26 is x = -1.396.

Let's assume the price of an adult ticket is t.
Given that Denny bought 3 child tickets, the cost of those child tickets would be 3 times the price reduction of $5 from the adult ticket price. So the total cost of the child tickets would be 3(t - $5).
The total amount Denny spent on tickets is given as $45.
Therefore, the equation that can be used to find the price of an adult ticket, t, would be:
3(t - $5) + t = $45
This equation represents the total cost of the child tickets plus the cost of one adult ticket being equal to $45.

To solve the equation 50(4x+12) = -200, we can start by distributing the 50 to the terms within the parentheses:
50 * 4x + 50 * 12 = -200
This simplifies to:
200x + 600 = -200
Next, we'll subtract 600 from both sides of the equation to isolate the term with x:
200x + 600 - 600 = -200 - 600
This gives us:
200x = -800
Finally, we divide both sides of the equation by 200 to solve for x:
200x / 200 = -800 / 200
This results in:
x = -4
Therefore, the solution to the equation 50(4x+12) = -200 is x = -4.
50 * 4x + 50 * 12 = -200
This simplifies to:
200x + 600 = -200
Next, we'll subtract 600 from both sides of the equation to isolate the term with x:
200x + 600 - 600 = -200 - 600
This gives us:
200x = -800
Finally, we divide both sides of the equation by 200 to solve for x:
200x / 200 = -800 / 200
This results in:
x = -4
Therefore, the solution to the equation 50(4x+12) = -200 is x = -4.

To solve the equation 1.5 - x = -4.5, let's isolate x on one side:
We'll start by subtracting 1.5 from both sides of the equation:
1.5 - x - 1.5 = -4.5 - 1.5
This simplifies to:
-x = -6
Next, we'll multiply both sides of the equation by -1 to solve for x:
(-1)(-x) = (-1)(-6)
This gives us:
x = 6
Therefore, x = 6 is the solution to the equation 1.5 - x = -4.5.
We'll start by subtracting 1.5 from both sides of the equation:
1.5 - x - 1.5 = -4.5 - 1.5
This simplifies to:
-x = -6
Next, we'll multiply both sides of the equation by -1 to solve for x:
(-1)(-x) = (-1)(-6)

To solve the equation 6y - 9y + 6 = -12, let's combine like terms on the left side:
6y - 9y + 6 = -12
(-3y + 6) = -12
Next, we'll subtract 6 from both sides of the equation:
-3y + 6 - 6 = -12 - 6
This simplifies to:
-3y = -18
Next, we'll divide both sides of the equation by -3 to solve for y:
(-3y) / -3 = (-18) / -3
This gives us:
y = 6
Therefore, y = 6 is the solution to the equation 6y - 9y + 6 = -12.
6y - 9y + 6 = -12
(-3y + 6) = -12
Next, we'll subtract 6 from both sides of the equation:

The first step in solving the equation 3 = 6y + 9 is to isolate the variable "y" on one side of the equation.
To do this, we'll start by subtracting 9 from both sides of the equation:
3 - 9 = 6y + 9 - 9
This simplifies to:
-6 = 6y
Now, to further isolate y, we need to divide both sides of the equation by 6:

This gives us:
-1 = y
Therefore, the solution to the equation 3 = 6y + 9 is y = -1.
