  1. Let s = Steve's age.

    s + (3s - 7) = 65
    4s - 7 = 65
    4s = 72
    s = 18

    Check:

    Steve is 18
    His mom is (3 * 18) - 7 = 54 - 7 = 47

    14 + 47 = 65

    Yep.

  3. Let M = mom's age
    let S = steve's age.

    M+S = 65
    3S = M+7
    solve for M and S.
    Check my thinking.
