5xy+4=9 is the problem, right? 5xy+4=9. Now subtract the 4 from both sides. 5xy=5. Ok, then, that looks less scary. Now, divide both sides by 5, to get xy=1. Hmm, a lot simpler. Now, divide both sides by x to get y by itself. So, y=1/x. Alright. That's your line! No, its not a straight line. There is a vertical asymptote where x=0, and the two segments aren't straight. But that's a simpler form of the equation. Hope that helped!

It is 5xy + 5x.

The GCF is 5xy.

(-5xy):(-xy)=

In the given expression you replace x by 2 and y by 1. Thus 5xy + 7x2 - 12y = 5*x*y + 7*x2 - 12*y = 5*2*1 + 7*22 - 12*1 = 10 + 28 - 12 = 26
