12x = 8x + 12
First you would subtract 8x from both sides
12x - 8x = 4x for the left side and it cancells out 8x on the right side.
Now we have 4x = 12. Divide 12 and 4 and your answer would be 3.
ANSWER: x = 3
Simplifying
12x + -8x = 12
Combine like terms: 12x + -8x = 4x
4x = 12
Solving
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.
x = 3
