    2: Solve the equation using addition or subtraction.
    5.5=-2+D

    A: d=5
    B: d=7.5
    C: d=5.5
    D: d=3.5

    3: Solve the equation using multiplication or division.
    -7y=28

    A: y=-4
    B: y=4
    C: y=14
    D: y=35

    4: Solve the equation using multiplication or division.
    -13= M over -5

    A: m= 13 over 5
    B: m= 45
    C: m= 65
    D: m= 5 over 13

    5: Solve the equation.
    3 over 4 * =9

    A: x=12
    B: x=108
    C: x=72
    D: x=4 over 9

    If you can help me solve these, I think I'll be able to understand and answer the rest myself.

  6. 2: Solve the equation using addition or subtraction.
    5.5=-2+D add 2 to both sides
    +2 = +2
    ----------------
    7.5 = -2+2 + D
    or
    7.5 = D

  7. 3: Solve the equation using multiplication or division.
    -7y=28 divide both sides by -7
    (-7/-7) y = 28/(-7)
    y = -28/7
    y = 4

  8. 4: Solve the equation using multiplication or division.
    -13= M over -5 = M/(-5)
    multiply both sides by -5
    -13 (-5) = M (-5/-5)
    65 = M

  9. 5: Solve the equation.
    3 over 4 * =9
    HUH ???
    maybe 3 / 4x = 9 ???? if so multiply both sides by 4 x
    3 = 36 x
    x = 1/12
    or maybe
    (3/4) x= 9 multiply both sides by 4/3
    x = 9*4/3 = 12

    A: x=12
    B: x=108
    C: x=72
    D: x=4 over 9
