Answer 2

Answer:

implifying

7x + -4 = 5x + 20

Reorder the terms:

-4 + 7x = 5x + 20

Reorder the terms:

-4 + 7x = 20 + 5x

Solving

-4 + 7x = 20 + 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.

-4 + 7x + -5x = 20 + 5x + -5x

Combine like terms: 7x + -5x = 2x

-4 + 2x = 20 + 5x + -5x

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

-4 + 2x = 20 + 0

-4 + 2x = 20

Add '4' to each side of the equation.

-4 + 4 + 2x = 20 + 4

Combine like terms: -4 + 4 = 0

0 + 2x = 20 + 4

2x = 20 + 4

Combine like terms: 20 + 4 = 24

2x = 24

Divide each side by '2'.

x = 12

Simplifying

x = 12
