Right now in math class we are learning rational expressions. Since I am in an advanced math class, it seems like we learn a new lesson everyday. So if you don't understand something, you pretty much need to teach yourself. I don't really understand rational expressions, so can someone tell me if I am doing these two problems right(If I am doing wrong please tell me how to do them.)(adsbygoogle = window.adsbygoogle || []).push({});

Problem: x/3 = 4/x+4

Answer: 1) First I found a common denominator.

3x+12(x/3) = 3x+12(4/x+4)

2) So I got x+4 = x+3

3) Then the answer would be x=-4, x=-3

Am I right?
