Answer:
2
Step-by-step explanation:
Simplifying
4x + -4 = 2x + -2
Reorder the terms:
-4 + 4x = 2x + -2
Reorder the terms:
-4 + 4x = -2 + 2x
Solving
-4 + 4x = -2 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
-4 + 4x + -2x = -2 + 2x + -2x
Combine like terms: 4x + -2x = 2x
-4 + 2x = -2 + 2x + -2x
Combine like terms: 2x + -2x = 0
-4 + 2x = -2 + 0
-4 + 2x = -2
Add '4' to each side of the equation.
-4 + 4 + 2x = -2 + 4
Combine like terms: -4 + 4 = 0
0 + 2x = -2 + 4
2x = -2 + 4
Combine like terms: -2 + 4 = 2
2x = 2
Divide each side by '2'.
x = 1
Simplifying
x = 1
