    q = 15

    Step-by-step explanation:

    →First, add 18q to both sides:

    -15 - 18q = - 20q + 15

    -15 = - 2q + 15

    →Subtract 15 from both sides:

    -30 = - 2q

    →Divide both sides by - 2:

    15 = q

    We first want to get q on its own then solve like shown:

    -15-18q=-20q+15

    Now add 15 to both sides and add 20 q to both sides.

    2q=30

    Now divide 30 by 2.

    q=15
