Let the number of pages Eva has read be labeled as "E".
If Liam has read 17 fewer pages than Eva, that means he has read "E-17" pages.
Now, if they read 265 pages combined, we can express this as the below equation:
Eva's pages + Liam's pages = 265 pages
E + (E-17) = 265
Now we can solve for Eva's pages, and that will help us figure out how many pages Liam read.
E + (E-17) = 265
2E -17 = 265
2E = 282
E = 141
Eva read 141 pages. Liam read 17 fewer pages than she did: 141 - 17 = 124.
Liam read 124 pages.
You can double check your work by adding Eva's pages and Liam's pages together and see if it comes out to 265.
141 + 124 = 265 - correct!
