Question 309626: Mary (m) is 4 years older than Rico (r). Ten years ago Mary was 3 times as old as Rico was then. a) how old are they now? b) determine if answer is correct by checking that it satisfies the conditions of the problem
I've got r = 4 = m and have to subtract 10 years from both and multiply both by 3?
3(r-10) = m -10
3r - 30 = m -10
m = 3r - 20
r + 4 = 3r -
4 + r = -20 + 3r (subtract 3r from both sides)
4 + -2r = -20 (subtract 4 from both sides)
-2r = -24 (divide both by -2) gives the solution of 12?
so if I was solving for r, then that is Rico's age 10 years ago?? He would be 22 now and if 4 years older, Mary would be 26? This can't be right if 10 years ago she was 3 times his age.
