x=3
Step-by-step explanation:
First, get your variables and constants separated on either side of the =
Whatever you do to one side, you have to do to the other.
12 + 5x = 18 + 3x
subtract 3x from both sides to cancel out the 3x on the right:
12 + 5x - 3x = 18 + 3x - 3x
12 + 2x = 18
subtract 12 from both sides to cancel out the 12 on the left side:
12 - 12 + 2x = 18 - 12
now just solve for x
2x = 6
divide both sides by 2 to cancel out the 2 on the left side:
2x / 2 = 6 / 2
x = 3

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
