    Simplifying

    2x + 128 = 180

    Reorder the terms:

    128 + 2x = 180

    Solving

    128 + 2x = 180

    Solving for variable 'x'.

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

    Add '-128' to each side of the equation.

    128 + - 128 + 2x = 180 + - 128

    Combine like terms: 128 + - 128 = 0

    0 + 2x = 180 + - 128

    2x = 180 + - 128

    Combine like terms: 180 + - 128 = 52

    2x = 52

    Divide each side by '2'.

    x = 26

    Simplifying

    x = 26
