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
