Answer: C
Step-by-step explanation:
5 + -2x = 4 + -2x + 4 + x
Reorder the terms:
5 + -2x = 4 + 4 + -2x + x
Combine like terms: 4 + 4 = 8
5 + -2x = 8 + -2x + x
Combine like terms: -2x + x = -1x
5 + -2x = 8 + -1x
Solving
5 + -2x = 8 + -1x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'x' to each side of the equation.
5 + -2x + x = 8 + -1x + x
Combine like terms: -2x + x = -1x
5 + -1x = 8 + -1x + x
Combine like terms: -1x + x = 0
5 + -1x = 8 + 0
5 + -1x = 8
Add '-5' to each side of the equation.
5 + -5 + -1x = 8 + -5
Combine like terms: 5 + -5 = 0
0 + -1x = 8 + -5
-1x = 8 + -5
Combine like terms: 8 + -5 = 3
-1x = 3
Divide each side by '-1'.
x = -3
Simplifying
x = -3
