    x = 2.2

    Step-by-step explanation:

    -15 + 12x = 5x + 7 - 3x

    Combine like terms

    -15 + 12x = 2x + 7

    Subtract 2x from each side

    -15 + 12x - 2x = 2x-2x + 7

    -15 + 10x = 7

    Add 15 from each side

    -15+15 + 10x = 7+15

    10x = 22

    Divide each side by 10

    10x/10 = 22/10

    x = 2.2

    Steps to solve:

    -15 + 12x = 5x + 7 - 3x

    ~Combine like terms

    -15 + 12x = (5x - 3x) + 7

    ~Simplify

    -15 + 12x = 2x + 7

    ~Add 15 to both sides

    -15 + 15 + 12x = 2x + 7 + 15

    ~Simplify

    12x = 2x + 22

    ~Subtract 2x to both sides

    12x - 2x = 2x - 2x + 22

    ~Simplify

    10x = 22

    ~Divide 10 to both sides

    10x/10 = 22/10

    ~Simplify

    x = 11/5 or 2.2

    Best of Luck!
