Question 1185649
 The difference in Alex and Toni’s ages is 5. The product of their ages is 104. 
If Alex is older, how old is Toni?
-----------
They're 8 & 13
======================
You can do it the long way:
x = Toni's age
---
x*(x+5) = 104
{{{x^2 + 5x - 104 = 0}}}
At this point, you factor 104 and get x = 8.  More steps to do the same.
