How do you solve 12+5x = 18+3x
guajiro [1.7K]

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
