Answer: x = 3
Step-by-step explanation:Simplifying
12 + 5x = 18 + 3x
Solving
12 + 5x = 18 + 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.
12 + 5x + -3x = 18 + 3x + -3x
Combine like terms: 5x + -3x = 2x
12 + 2x = 18 + 3x + -3x
Combine like terms: 3x + -3x = 0
12 + 2x = 18 + 0
12 + 2x = 18
Add '-12' to each side of the equation.
12 + -12 + 2x = 18 + -12
Combine like terms: 12 + -12 = 0
0 + 2x = 18 + -12
2x = 18 + -12
Combine like terms: 18 + -12 = 6
2x = 6
Divide each side by '2'.
x = 3
Simplifying
x = 3
