Question 1020721
Justin is 5 years more than half of the age of charlie. 
Six years from now, justins ages is seven less than charlie,'s age. How old is charlie now 
-----------------
Equations:
j = (1/2)c + 5
j+6 = (c+6)-7
-------------------------
Substitute for "j" and solve for "c"::
(1/2)c + 5 + 6 = c-1
----
(1/2)c + 11 = c-1
(1/2)c = 12
charlie = 24 yrs
