Can someone please help me with the solution to this question that was under Arithmetic and Algebra Session 8 for homework. I can’t find the solution in any of the following sessions and this one was really difficult for me. I would appreciate a step by step way that you went about the problem and not merely the answer if that’s possible.

Please share *your* approach first. That way we can correct any errors you have in your mind.

Thanks for the advice. My first approach was to relate the two equations somehow but I got stuck. I just now thought to try another approach which was guessing values for x and I think I was able to get the right answer. Now I guess my question would be is there a faster or better way to solve this problem.

The hint here is that the options are all in terms of x, so you don’t need to find x specifically. Try multiplying both sides of the equation by x.
