Answer:
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Step-by-step explanation:
Let
x -----> number of pages that Polina read
y ----> number of pages that Marcus read
we know that
x+y=108 ----> equation A
x=5y -----> equation B
substitute equation B in equation A and solve for y
[tex]5y+y=108\\6y=108\\y=18[/tex]
Find the value of x
[tex]x=5y -----> x=5(18)=90[/tex]
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
