In x years, we will have
6m+x = 2(m+x)
6m+x = 2m+2x
4m = x
So, no matter what Mary's age is now, in 4 times that many years Nancy will only be twice as old.
For example, if Mary is now 5,
Mary is 5 and Nancy is 30
In 20 years, Mary will be 25 and Nancy will be 50.
6m+x = 2(m+x)
6m+x = 2m+2x
4m = x
So, no matter what Mary's age is now, in 4 times that many years Nancy will only be twice as old.
For example, if Mary is now 5,
Mary is 5 and Nancy is 30
In 20 years, Mary will be 25 and Nancy will be 50.
