And it's impossible to solve for y, as there's 3 variable and only 1 equation.

Simply subtract all the terms out that don't contain y, and then factor out the yterm and divide both sides by all the nony stuff to isolate it.

So here is an example: 2xy+3yx=0 take out all the nony terms to try to isolate them by subtracting them from both sides. 2xy+3y=x now factor out the y y(2x+3)=x divide out the nony stuff! y=x/(2x+3) there you go, that example should help you out!

So basically all you're doing here is trying to get y all by itself, you're solving for y, right? Follow what the guy up there did to get y into an easier form to look like this, −2ay−2a+2y−2b=0 This way you won't have to deal with fractions or anything weird. When you do that, you will notice that some of the terms have a y in them and some don't. So then you can subtract the terms without y in them so they're on the other side. When they're on the other side, you can divide y out. for example if you have y(2x+3) if you multiply that out you get 2xy+3y, so really you're just going backwards to try to extract the y from it.

use the rule if...\[\Large \frac mn = \frac pq\] then ...\[\Large {m+n \over mn}={p+q \over p q}\] ...the inverse is also true

or if you are using zepp's equations ... they are only right til the 2nd step \[(y1)(a+b)=(y+1)(ab) \]\[\implies a(y1)+b(y1)=a(y+1)b(y+1) \]\[\implies \Large \cancel{ay}a+by\cancel b=\cancel{ay}+aby\cancel b\] now: bring all the terms with y on one side of the = sign, and all nony terms to the other\[\implies \Large 2b \cdot y=2a\]\[\Large \implies y= \frac ab\]
