    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
