Yancy wrote two novels that together contain 580 pages. His longer novel has 160 pages more than his shorter novel. How many pages are contained in Yancy's shorter novel?
How about:
let the number of pages in the shorter book be n
then the number of pages in the longer book must be n+160, ( they told us that)
"together" they contain 580 pages ....
n + n+160 = 580
etc
