  4. #3
    4x + 8y - 3x + 2 y
    = 4x - 3x + 8y + 2y
    = x + 10y

    the others from #1 to #12 are correct

    #13
    let number of bottles in a case be x
    so you have 4x + 8 bottole
    4x+8 = 104
    4x = 96
    x = 24

    #14 , ok

    #15
    z – 4 > 9
    add 4 to both sides
    z > 13

    #16

    q + 7 ≤ – 15 , subtract 7 from both sides
    q ≤ -22

    #17
    -3y > 9 , divide by -3, so you MUST reverse the inequality sign
    y < -3

    #18
    k/5 ≥ -4 , multiply both sides by +5
    k ≥ -20

    #19
    4g – 8 < 20
    4g < 28
    g < 7

    #20
    v/-2 + 12 ≤ 8 , subtract 12
    v/-2 ≤ -4 , multiply by -2, reverse inequality sign
    v ≥ 8

    For the most part, when working with inequalities, pretend they are equations and perform the same steps, EXCEPT when multiplying or dividing by a negative, you must reverse the inequality sign.
    This is usually your last step
