Answer:
Explanation:
Simplifying 
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
