    The answer to your question is r = 3

    Step-by-step explanation:

    2r - 15 = - 9r + 18

    Process

    1. - Add 9r in both sides

    2r + 9r - 15 = - 9r + 18 + 9r

    2. - Simplify

    11r - 15 = 18

    3. - Add 15 to both sides

    11r - 15 + 15 = 18 + 15

    4. - Simplify

    11r = 33

    5. - Divide both sides by 11

    11/11 r = 33/11

    6. - Simplify and result

    r = 3
