Two workers can build a house in 4 days. One worker can build the house by himself in 6 days. How long would it take the other worker to build the house by himself? Can you solve this easy algebra word problem?

My name is Chris and my passion is to teach math. Learning should never be a struggle which is why I make all my videos as simple and fun as possible. I cover all subjects from basic level math through upper level calculus and statistics. I also make brain teaser, word problems, and Rubik's cube videos for fun.

Check out some of my other videos if you want.
