Let
x------> the number of multiple choice question
y------> the number of free response question
we know that
-----> equation A

-----> equation B
Substitute equation B in equation A
Find the value of x


therefore
<u>the answer is</u>
the number of multiple choice question are 
the number of free response question are 
let's set up an equation:
x-4=9
solve normally:
x=13
Da answer is cCbecause it is
-[4] [2] [-4] [-8]
mark me brainliest if i right ty :))
