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
![5y+y=108\\6y=108\\y=18](https://tex.z-dn.net/?f=5y%2By%3D108%5C%5C6y%3D108%5C%5Cy%3D18)
Find the value of x
![x=5y -----> x=5(18)=90](https://tex.z-dn.net/?f=x%3D5y%20-----%3E%20x%3D5%2818%29%3D90)
therefore
The number of pages that Polina read was 90 and the number of pages that Marcus read was 18
Pretty sure it’s b, good luck
