I have a question on my homework, it is on Applications of Linear Systems, the question is : You plant a 14-inch hemlock tree in your backyard that grows at a rate of 4 inches per year and an 8-inch blue spruce tree that grows at a rate of 6 inches per year. In how many years after you plant the trees will the two trees be the same height? how tall will each tree be?(adsbygoogle = window.adsbygoogle || []).push({});

I know the answer: 3 years, both 26 inches, I dont know how to write out the systems, maybe I'm just an idiot, I don't know.
