Shelly is 3 years older than Michele. Four years ago the sum of their aages was 67. Find the age of each person now.
Answer provided by our tutors
let 'x represent Michele's age, then 'x+3' represents Shelly's age
(x-4) + (x+3-4) = 67
solving for 'x' we have x=36
36+3 = 39
Michele is 36, Shelly is 39
