    no solutions

    Step-by-step explanation:

    -8x + x + 15 = - 7x + 12

    Combine terms

    -8x + x + 15 = - 7x + 12

    -7x + 15 = - 7x + 12

    Add 7x to each side

    15 = 12

    This is never true so there are no solutions

    Steps to solve:

    -8x + x + 15 = - 7x + 12

    ~Combine like terms

    -7x + 15 = - 7x + 12

    ~Add 7x to both sides

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

    ~Simplify

    15 = 12

    There are no solutions.

    Best of Luck!
