Professor Homunculus replies: Hi, Reader, I must say that it is a good thing that it is not taught online. Specific problems should never be shown online. That would be show-and-tell, not teaching. What you need to learn is the concepts behind the problems, then you’ll be able to crack all problems that are similar. One of the concepts is a very interesting and important part of algebra. Here’s a way to start figuring out how to solve your problem: |
