    s=2/3

    Step-by-step explanation:

    15 (s - 3) = 12s - 43

    distribution

    15s-45=12s-43

    minus 12s from both sides

    3s-45=-43

    add 45 to both sides

    3s=2

    divide both sides by 3

    s=2/3

    substitute to prove right

    15 (2/3-3) = 12 (2/3) - 43

    10-45=8-43

    -35=-35

    s = 2/3

    Step-by-step explanation:

    15 (s - 3) = 12s - 43

    15s - 45 = 12s - 43

    15s - 12s = - 43 + 45

    3s = 2

    s = 2/3
