*5/x-2/3=8/x-7/6,*we would get: So, to summarize, if you do not want to subtract equations, you can always change the sign on EVERY term in

**5/x-2/3=8/x-7/6**second equation and add the equations. Now, we can set the right hand side of each equation equal to each other because they both equal y. Make sure that you can work through this example and get the

*5/x-2/3=8/x-7/6*answers. The bottom line is that you want

*5/x-2/3=8/x-7/6*make both x- or y-coefficients opposites or the same, if yo want to subtract of each. What does that mean? Could you tell that from the graph?
