Question 701493
 Lily and John are cousins. Lily is 7 years older than John, and John is under five. If Lily’s sister Miranda is the same age as Lily and John’s ages put together, how old is Miranda?

------------------------
Equations/ Inequalities:
L = J + 7
J < 5
--
M = L+J
-----
Substitute for "L":
M = J+7 + 7
---
Miranda = J + 14
---
Since J < 5, Miranda < 19
