  2. x=total
    x
    x/3= --
    3
    x ( x )
    -- +1=( -- + 1)
    3 ( 3 )

    192/3=64
    64+2+66
    64-2=62
    Ans: 66, 64, 62

  7. X = total
    Betty: Y
    Audrey: Y + 2
    Christine: Y - 2

    Y + (Y + 2) + (Y -2) = 3Y
    3Y = X
    192/3 = 64(Y)
    64 + 2 = 66
    64 - 2 = 62
    Audrey: 66
    Betty: 64
    Christine: 62

  8. Audrey=y+2
    Betty=y
    Christine=y-2
    192=y+2+y+y-2
    =y+y+y+2-2
    192=3y

  9. Audrey-->y+2
    Betty-->y
    Christine--> y-2
    Total age=y+y+y+2-2= 3y
    192+2+2+2=198
    198 divide by 3= 66
    Audrey=66
    Betty=66-2=64
    Christine=66-2-2=62

    Y=64

    Betty:64
    Audrey:66 (64+2)
    Christine: 62 (64-2)
