Changed it since i figured it out already and theirs no way to delete it. 

6 questions are worth 5 point and 4 are worth 2. i figured this out because 5 times 6 is 30 and 2 times 4 is 8 which makes 38.

replace   c   with   a   and simplify.

a = c , b = a, q = n , 2 , a = c , 900 b= a , 700 , q = n , 600 , 2 = b o t h , b = a , q = n
