Answer:
X=16
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
