    x = 3

    Step-by-step explanation:

    1. Expand.

    -3x - 12 + 15 = 6 - 4x

    2. Simplify - 3x - 12 + 15 to - 3x + 3.

    -3x + 3 = 6 - 4x

    3. Subtract 3 from both sides.

    -3x = 6 - 4x - 3

    4. Simplify 6 - 4x - 3 to - 4x + 3.

    -3x=-4x+3

    5. Add 4x to both sides.

    -3x + 4x = 3

    6. Simplify - 3x + 4x to x.

    x = 3
