Answer:

X=16

Step-by-step explanation:

Solving for variable 'x'.

Add '-6x' to each side of the equation.

20 + 4x + -6x = -12 + 6x + -6x

Combine like terms: 4x + -6x = -2x

20 + -2x = -12 + 6x + -6x

Combine like terms: 6x + -6x = 0

20 + -2x = -12 + 0

20 + -2x = -12

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

20 + -20 + -2x = -12 + -20

Combine like terms: 20 + -20 = 0

0 + -2x = -12 + -20

-2x = -12 + -20

Combine like terms: -12 + -20 = -32

-2x = -32

Divide each side by '-2'.

x = 16

Simplifying

x = 16
