    #1
    5h – 9 = –16 + 6h
    -h = -7
    h = 7

    #2
    4x + 4 = 9x – 36
    -5x = -40
    x = 8

    #3
    7x + 5 = 4x + 5 + 3x
    7x+5 = 7x+5
    true for all x

    #4
    place a solid dot at x = -2
    Shade to the left

    #5
    k < 0

    #6
    q – 12 ≥ –13
    q >= -1

    #7
    12p < 96
    p < 8

    #8
    g/–5 < –18
    g > 90

    #9
    n-6 >= 2
    n >= 8

    #10
    11.99x <= 59.95
    x <= 5

    If you had no clue on solving these, I fear you are not ready for your quiz. Lots of work ahead, babe.

    1) 5h ¨C 9 = ¨C16 + 6h
    -9+16 = 6h-5h
    7 = h

    4x + 4 = 9x ¨C 36
    36 +4 = 9x-4x
    40 = 5x

    8 =x
    5) k < 0
    6) q ¡Ý ¨C1
    7) p < 8
    8)g > 90
    9)n ¨C 6 ¡Ý 2; n ¡Ý 8
