Ricky is 5 years older than Sara. Three years ago he was twice her age. How old is Ricky? Thanks for the help!

  • math -

    r=s+5
    r-3 = 2(s-3)

    (r,s)=(13,8)

  • math -

    Sarah is 8, Ricky is 13

    age now age 3 yrs ago
    Sara x x - 3

    ricky x + 5 (x+5)-3

    so (x+5-3)= 2*(x-3)
    x+2=2x-6
    x=8
