Problema Solution

John is 3 times older than Mary and twice as old as Ellen. Total ages is 11. What are ages

Answer provided by our tutors

Let 'j', 'm', and 'e' stand for the ages of John, Mary, and Ellen. We can write:


j=3m

j=2e

j+m+e=11


Using Algebrator to solve for 'e', 'j', and 'm', we get:

e=3

j=6

m=2
