    x = - 9

    Step-by-step explanation:

    I'm sorry, but I won't be explaining it, however I will show every step.

    Let's begin.

    4x - 12 = - 7x - 111

    4x - 12 + 7x = - 7x - 111 + 7x

    11x - 12 = - 111

    11x - 12 + 111 = - 111 + 111

    11x + 99 = 0

    11x + 99 - 99 = 0 - 99

    11x = - 99

    11x/11 = - 99/11

    x = - 9
