    x=23

    Simplifying

    (3x + - 50) + (7x)

    Reorder the terms:

    (-50 + 3x) + (7x)

    Remove parenthesis around (-50 + 3x)

    -50 + 3x + (7x) =

    Combine like terms: 3x + (7x)

    -50 + 10x

    Solving

    -50 + 10x

    Solving for variable 'x'.

    Move all terms containing x to the left, all other terms to the right.

    Add '50' to each side of the equation.

    -50 + 50 + 10x = 180 + 50

    Combine like terms: - 50 + 50 = 0

    0 + 10x = 180 + 50

    10x = 180 + 50

    Combine like terms: 180 + 50 = 230

    10x = 230

    Divide each side by '10'.

    Simplifying

    x = 23
