Answer:
x = 5
Step-by-step explanation:
Simplifying
6x + -3 = 3x + 12
Reorder the terms:
-3 + 6x = 3x + 12
Reorder the terms:
-3 + 6x = 12 + 3x
Solving
-3 + 6x = 12 + 3x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-3x' to each side of the equation.
-3 + 6x + -3x = 12 + 3x + -3x
Combine like terms: 6x + -3x = 3x
-3 + 3x = 12 + 3x + -3x
Combine like terms: 3x + -3x = 0
-3 + 3x = 12 + 0
-3 + 3x = 12
Add '3' to each side of the equation.
-3 + 3 + 3x = 12 + 3
Combine like terms: -3 + 3 = 0
0 + 3x = 12 + 3
3x = 12 + 3
Combine like terms: 12 + 3 = 15
3x = 15
Divide each side by '3'.
x = 5
