Answer :

Simplifying

5x + 20 = 9x + -8

Reorder the terms:

20 + 5x = 9x + -8

Reorder the terms:

20 + 5x = -8 + 9x

Solving

20 + 5x = -8 + 9x

Solving for variable 'x'.

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

Add '-9x' to each side of the equation.

20 + 5x + -9x = -8 + 9x + -9x

Combine like terms: 5x + -9x = -4x

20 + -4x = -8 + 9x + -9x

Combine like terms: 9x + -9x = 0

20 + -4x = -8 + 0

20 + -4x = -8

Add '-20' to each side of the equation.

20 + -20 + -4x = -8 + -20

Combine like terms: 20 + -20 = 0

0 + -4x = -8 + -20

-4x = -8 + -20

Combine like terms: -8 + -20 = -28

-4x = -28

Divide each side by '-4'.

x = 7

Simplifying

x = 7
