    r = - 5/9

    Step-by-step explanation:

    distribute the 5/2 to the (8r - 6) so you get

    7 - 20r + 15 + 2r = 32

    combine like terms to get

    -18r + 22 = 32

    subtract 22 to both sides and you end up with

    -18r = 10

    divide both sides by - 18 and you end up with

    r = - 0.5 repeating or - 5/9 as a simplified fraction
