    Simplifying

    7x + - 10x + 18 + 2x = - 5

    Reorder the terms:

    18 + 7x + - 10x + 2x = - 5

    Combine like terms: 7x + - 10x = - 3x

    18 + - 3x + 2x = - 5

    Combine like terms: - 3x + 2x = - 1x

    18 + - 1x = - 5

    Solving

    18 + - 1x = - 5

    Solving for variable 'x'.

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

    Add '-18' to each side of the equation.

    18 + - 18 + - 1x = - 5 + - 18

    Combine like terms: 18 + - 18 = 0

    0 + - 1x = - 5 + - 18

    -1x = - 5 + - 18

    Combine like terms: - 5 + - 18 = - 23

    -1x = - 23

    Divide each side by '-1'.

    x = 23

    Simplifying

    x = 23
