<span>Simplifying
6x + (x + -2) = 180
Reorder the terms:
6x + (-2 + x) = 180
Remove parenthesis around (-2 + x)
6x + -2 + x = 180
Reorder the terms:
-2 + 6x + x = 180
Combine like terms: 6x + x = 7x
-2 + 7x = 180
Solving
-2 + 7x = 180
Solving for variable 'x'.
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
Simplifying
x = 26</span>
