------------------------------------------
Evan is 5 years older than Kathryn.
------------------------------------------

v, Evan now
k, Kathryn now
k=v-5


-----------------------------------------------
In 8 years the sum of their ages will be 47.
-----------------------------------------------
v%2B8%2B%28v-5%2B8%29=47


---------------------------
How old is Evan now?
---------------------------
Just solve the previous equation.
v%2Bv%2B8%2B8-5=47
2v=47-16%2B5
2v=47-11
2v=36
highlight%28v=18%29
