Hi

"Joel is two years older than Sarah.  Sarah is two years older than Michael. 

 

Let x and (x+2) and (x+4) represent Michael's, Sarah's and Joel's ages resepctively

Question states***The sum of their ages is 63

x+(x+2)+(x+4) = 63

   3x+6 = 63

     x = 19, Michael's age, Sarah 21 and Joel 23

CHECKING our Answer***

  19 + 21 + 23 = 63

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
