We solve some applications of linear equations. In particular, we solve the following two work problems:
1. Andy can paint a fence in 4 hours, and Ben can do the job in 6 hours. If they work together, how long will it take them to paint the fence?
2. One pipe can fill a tank twice as fast as a second pipe. When both pipes are opened, they fill the tank in 9 minutes. How long would it take to fill the tank if only the faster pipe is used?
