Question 203451: Using some pages that hold 1300 words per page and others that hold 1850 words per page, a typesetter is able to completely fill 12 pages with an 18,350-word document. How many pages of each kind were used?

let x = 1300 word pg=7
let 12-x=1850 word pg=5
1300x+1850(12-x)=18350
1300x+22200-1850x=18350
1300x-1850x=18350-22200
-550x=-3850
x=7
