Simplifying

4x + -5 = 2x + 7

Reorder the terms:

-5 + 4x = 2x + 7

Solving

-5 + 4x = 7 + 2x

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

Add '-2x' to each side of the equation.

-5 + 4x + -2x = 7 + 2x + -2x

Combine like terms: 4x + -2x = 2x

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

Combine like terms: 2x + -2x = 0

-5 + 2x = 7 + 0

-5 + 2x = 7

Add '5' to each side of the equation.

-5 + 5 + 2x = 7 + 5

Combine like terms: -5 + 5 = 0

0 + 2x = 7 + 5

2x = 7 + 5

Combine like terms: 7 + 5 = 12

2x = 12

Divide each side by '2'.
