your mistake occurred on the line in red. you should have, instead, get all terms with y in them on one side and factor out the y, then divide through by the thing you have multiplying y. though, you could still do it in your last line. it will be messier than it has to be though

Could you please show me how?

I did what you said and got the following. . .



And now. . .I don't know what to do. . .I don't know how to isolate for the variable with two terms that aren't the same on one side. . .
