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 \(2\)
