Question

Shelly is 3 years older than Michele. Four years ago the sum of their age was 67. Find the age of each person.

Answer 1

It's is 36 I think I am not sure

Answer 2

total of ages now is 67 + 4 + 4 = 75

S=shelly

M= Michelle

Michelle is 3 yrs younger than Shelly so use S-3

S +M = 75

replace M with S-3 to get:

S +S-3=75

2S=78

s=39

So shelly is 39

Michelle is 3 years younger = 39-3 = 36
