Simplify 6x + (x + -2) = 180
6x + (-2 + x) = 180
Remove parenthesis around (-2 + x) 6x + -2 + x = 180
Reorder -2 + 6x + x = 180
Combine like terms: 6x + x = 7x -2 + 7x = 180
-2 + 7x = 180
Move all terms containing x to the left, all other terms to the right.
Add '2' to each side of the equation. -2 + 2 + 7x = 180 + 2
Combine like terms: -2 + 2 = 0 0 + 7x = 180 + 2 7x = 180 + 2
Combine like terms: 180 + 2 = 182 7x = 182
Divide each side by '7'. x = 26
Simplified answer x = 26
