    Step-by-step explanation:

    Simplifying

    2x + 9x + - 2 = 31

    Reorder the terms:

    -2 + 2x + 9x = 31

    Combine like terms: 2x + 9x = 11x

    -2 + 11x = 31

    Solving

    -2 + 11x = 31

    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 + 11x = 31 + 2

    Combine like terms: - 2 + 2 = 0

    0 + 11x = 31 + 2

    11x = 31 + 2

    Combine like terms: 31 + 2 = 33

    11x = 33

    Divide each side by '11'.

    x = 3

    Simplifying

    x = 3
