is it this question?

Students are given 3 minutes to complete each multiple-choice question on a test and 8 minutes for each free-response question. There are 15 questions on the test and the students have been given 55 minutes to complete it.

Because i've heard of this before.

[I Tried to be as neat as I could]

Let

x = the number of multiple choice question

y = the number of free response question

we know that

3x + 8y = 55 = Equation A

x+y=15

x = 15 - y = Equation B

Substitute equation B in equation A

3[15-y] + 8y = 55

45 - 3y+ 8y = 55

5y = 55 - 45

5y = 10

y = 2

Find the value of x

x = 15 - y

x = 15-2= 13

therefore

the answer is

the number of multiple choice question are 13

the number of free response question are 2

The process is really tedious but here is my answer(it might not be right)
