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?

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
