Question

Melissa is 24 years younger than joyce. In 2 years, Joyce will be 3 times as old as Melissa will be then. How old are they now?

Answer 1

m = j - 24
j = m +24
3(m + 2) = j + 2
// Setting up our formulas from given info

3m+6 = j +2
//simplify

3m +6 = j +2
3m + 6 = m+24 +2
//substituting

3m + 6 = m +26
3m = m +20
3m - m = 20
2m = 20
m =10

m = j - 24
//take one of the first formulas
//substitute 10 for m
10 = j -24
34 = j
j = 34
