    Step-by-step explanation:

    Solve the equation for x:

    3 (x + 5) = - 4x + 8

    Distribute.

    3x + 15 = - 4x + 8

    Combine like terms.

    3x + 15 = - 4x + 8

    +4x + 4x

    7x + 15 = 8

    -15 - 15

    7x = - 7

    Divide both sides by 7.

    x = - 1

    The following equation has one solution, x = - 1.
