Answer 4

Reorder the terms:
-2 + 4x + -2x = -42

Combine like terms: 4x + -2x = 2x
-2 + 2x = -42

Solving
-2 + 2x = -42

Add '2' to each side of the equation.
-2 + 2 + 2x = -42 + 2

Combine like terms: -2 + 2 = 0
0 + 2x = -42 + 2
2x = -42 + 2

Combine like terms: -42 + 2 = -40
2x = -40

Divide each side by '2'.
x = -20

Simplifying
x = -20
