Question 608487
Joel is two years older than Sarah. Sarah is two years older than Michael. The sum of their ages is 63. How old are Joel, Sarah, and Michael? "
--------
Equations:
j = s + 2
s = m + 2
j + s + m = 63
----
Substitute and solve for "s":
(s+2) + s + (s-2) = 63
3s = 63
sarah's age = 21
----
Joel = s+2 = 23
Michael = s-2 = 19
