Answer:
Leo is 10, Jenny is 20
Step-by-step explanation:
Let's say that Jenny's current age is j, and that Leo's current age is l. With this, we can set up the following equations:
j=2l
j-5=3(l-5)
Let's use substitution and plug the first equation into the second one:
(2l)-5=3(l-5)
2l-5=3l-15
l=10
j=20
Hope this helps!
