Simplifying: 4x + 52 + 8x + -10 = 90
Reorder the terms: 52 + -10 + 4x + 8x = 90
Combine like terms: 52 + -10 = 42 42 + 4x + 8x = 90
Combine like terms: 4x + 8x = 12x 42 + 12x = 90
42 + 12x = 90
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-42' to each side of the equation. 42 + -42 + 12x = 90 + -42 Combine like terms: 42 + -42 = 0
0 + 12x = 90 + -42
12x = 90 + -42
Combine like terms: 90 + -42 = 48
12x = 48
Divide each side by '12'. x = 4 from https://www.geteasysolution.com/4x+52+8x-10=90
