Answer 1

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
