There were 156 more children than adults at a carnival. When 42 children joined in and 26 adults left the carnival, there were 5 times as many children as adults left. How many children were there at the carnival at first?
+36916 Here is how to doo-doo....
Initially
c = 156 + a
Then
c+ 42 = 5 ( a - 26) Sub in the red equation
(156+a) + 42 = 5a - 130
a = 82 then c = 238
