Keith and Pete, have been assigned a workbook to complete at their own pace. They get together at Keith's house after school to complete as many pages as they can. Keith has already completed 70 pages and will continue working at a rate of 3 pages per hour. Pete has completed 80 pages and can work at a rate of 2 pages per hour. Eventually, the two students will have completed the same number of pages. How long will that take?

Write a system of equations and graph them.

70 + 3x  =  80 + 2x

 

3x - 2x =  80  - 70

 

x  = 10    hours
