12(m+5)=150
12 Left Parenthesis m plus 5 Right Parenthesis equals 150
12m+5=150
12 m plus 5 equals 150
m+12(5)=150
m plus 12 Left Parenthesis 5 Right Parenthesis equals 150

The equation -2(4-n) = 24 can be simplified as follows:
-2 * 4 = -8
-2 * (-n) = 2n
The equation becomes:
-8 + 2n = 24
To isolate the variable, we need to move -8 to the other side of the equation. By adding 8 to both sides, we get:
2n = 32
Finally, to solve for n, we divide both sides by 2:
n = 16
So the answer is 16.
-2 * 4 = -8
-2 * (-n) = 2n
The equation becomes:
-8 + 2n = 24
To isolate the variable, we need to move -8 to the other side of the equation. By adding 8 to both sides, we get:
2n = 32
Finally, to solve for n, we divide both sides by 2:
n = 16
So the answer is 16.

Let's set up the equation to solve for the number:
One-quarter of the difference of a number and 3 is 2 can be expressed as (1/4)(x-3) = 2.
To solve for x, we can multiply both sides of the equation by 4 to get rid of the fraction:
4 * (1/4)(x-3) = 4 * 2
Simplifying, we have:
(x - 3) = 8
Next, we isolate x by adding 3 to both sides of the equation:
x = 8 + 3
x = 11
Therefore, the number is 11.

To solve the equation (2/3)(x - 6) = 14, we'll begin by isolating the variable x.
First, we can multiply both sides of the equation by the reciprocal of 2/3, which is 3/2.
(3/2) * (2/3)(x - 6) = (3/2) * 14
Simplifying, we have:
(x - 6) = 21
Next, we'll isolate x by adding 6 to both sides of the equation:
x = 21 + 6
x = 27
Therefore, the solution to the equation is x = 27.

Next, we'll isolate x by adding 6 to both sides of the equation:
x = 21 + 6
x = 27
Therefore, the solution to the equation is x = 27.
