Mary's age is 2/3 that of peter's. two years ago mary's age was 1/2 of what peter's age will be in 5 years tim. how old is peter now?

  • math -

    Mary is 14 and Peter is 23

    To figure out Peter's age:

    x=Peter's age

    2/3(x-2)= 1/2(x+5) solve for x
    2/3x - 4/3 = 1/2x + 5/2
    2/3x-1/2x = 5/2+4/3
    4/6x-3/6x=15/6+8/6
    1/6x=23/6
    X=23/6 / 1/6
    X=23
