An office has an old copy machine and a new one. Working together, it takes both machines 6 hours to make all the copies of the annual Financial report. Working alone, it takes the old copy machine 5 hours longer than the new one to make all the copies of the report. How long will it take would it take the new copying machine to make all the copies working alone?

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)
