Answer 1

Answer:

3x + -7 = 5x + 12

Reorder the terms:

-7 + 3x = 5x + 12

Reorder the terms:

-7 + 3x = 12 + 5x

Solving

-7 + 3x = 12 + 5x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-5x' to each side of the equation.

-7 + 3x + -5x = 12 + 5x + -5x

Combine like terms: 3x + -5x = -2x

-7 + -2x = 12 + 5x + -5x

Combine like terms: 5x + -5x = 0

-7 + -2x = 12 + 0

-7 + -2x = 12

Add '7' to each side of the equation.

-7 + 7 + -2x = 12 + 7

Combine like terms: -7 + 7 = 0

0 + -2x = 12 + 7
