    x = - 5

    Step-by-step explanation:

    Performing the indicated multiplication, we get

    -3 = 3x - 18 - 6x.

    Combining the x terms, we get

    -3 = - 3x - 18

    Combining the constants, we get

    3x = 3 - 18, or 3x = - 15.

    Dividing both sides yields x = - 5.

    Multiply the bracket by 3

    -3 = 3x-18-6x

    -3 = 3x-6x-18 - just rearranging.

    -3 = - 3x-18

    Move - 18 to other side. Sign changes from - 18 to + 18.

    -3+18 = - 3x-18+18.

    15 = - 3x

    Divide by - 3 to get positive x.

    15/-3 = - 3x/-3

    x = - 5

    Answer: x = - 5
