  4. 2) 12p < 96
    ===========================
    divide both sides by 12
    p < 8 which is A
    ========================

    a. p < 8
    b. p < 108
    c. p < 84 ****** NO a
    d. p < -8

    3) g / -5 < -18
    ================================
    multiply both sides by -5
    WHEN YOU MULTIPLY BY NEGATIVE REVERSE THE ARROW!!!!
    g > 90
    Which is C
    ===================================

    a. 9 < -23
    b. g > -90 **********
    c. g > 90
    d. g < 90

    4) Which of the following equations has an infinite number of solutions?

    a. 3x - 3 = -4x
    b. 2y + 4 - y = 16
    c. 7x + 5 = 4x + 5 + 3x ******* YES
    d. 6y - 2 = 2(y - 1)

    5) The result of 6 subtracted from a number n is at least 2.

    a. n - 2 > 6; n > 8 ******* no
    b. n - 6 > 2; n > 8 I think this ! but>/=
    c. n + 6 > 2; n < 4
    d. n + 6 > 2; n > 4
