Answer:
12 + 3x = 24
Explanation:
Simplifying
3x + 12 = 24
Reorder the terms:
12 + 3x = 24
Solving
12 + 3x = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 3x = 24 + -12
Combine like terms: 12 + -12 = 0
0 + 3x = 24 + -12
3x = 24 + -12
Combine like terms: 24 + -12 = 12
3x = 12
Divide each side by '3'.
x = 4
Simplifying
x = 4
