Question 253939
the mother is getting younger.
now she is 40 times in 5 years she will be only three times as old as her daughter

(40+x)=3(10+x)
40+x=30+3x
10=2x
5=x

How long before she is only twice as old?
same equation but with  a 2 instead of 3
(40+x)=2(10+x)
40+x=20+2x
20=x
mom will be 60 and daughter will be 30
I joke with my kids that someday we will be the same age.
