    40 + 10x = 5x - 30

    To begin isolating x, subtract 40 from both sides.

    40 + 10x - 40 = 5x - 30 - 40

    10x = 5x - 70

    Subtract 5x from both sides.

    10x - 5x = 5x - 70 - 5x

    5x = - 70

    Finally, divide both sides by 5.

    5x/5 = - 70/5

    x = - 14

    Answer:

    x = - 14
