    Simplifying

    2x + 3 + 7x = - 24

    Reorder the terms:

    3 + 2x + 7x = - 24

    Combine like terms: 2x + 7x = 9x

    3 + 9x = - 24

    Solving

    3 + 9x = - 24

    Solving for variable 'x'.

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

    Add '-3' to each side of the equation.

    3 + - 3 + 9x = - 24 + - 3

    Combine like terms: 3 + - 3 = 0

    0 + 9x = - 24 + - 3

    9x = - 24 + - 3

    Combine like terms: - 24 + - 3 = - 27

    9x = - 27

    Divide each side by '9'.

    x = - 3

    Simplifying

    x = - 3
