Question 246116: Ralph is putting together a scrapbook, he puts four picture on each page and has three pictures left. If he started with 55 pictures, write and solve an equation to find how many pages have four pictures.
The instructor "told" us the answer was 13 but I'm not so good with word problems, I've tried: 3x+4=13,3x-4=13,4x-55=13,4x-13,etc and now I'm stumped

You can put this solution on YOUR website! Let x = number of pages
If there are 4 pictures per page with 3 left over, then
4x+3=55
Subtract 3 from each side:
4x=52
Divide by 4:
x=13
