What is preventing you from swapping x and y and resolving for y?

Can you swap x and y? Show me that.
That's it. Now solve for y. You probably want to add 1 to both sides, first.
i got 3x+1=y but I don't think thats right?
I did x + 1 = 3/(y-2)
multiplied both sides by three (is that correct?)
then got 3x + 3 = y -2
3x + 1 = y
x + 1 = 3/(y+2)
This is good. Now, there are several ways to go about this next step. The easiset might just be the reciprocal.
Example: If z = w, and neither is zero, we can conclude that 1/z = 1/w, right?
uhh, would i make it x + 1 = (y + 2)/3 then?
No, you did the reciprocal on only one side.
1/(x+1) = (y+2)/3
Now multiply by 3 and subtract 2.
When we did that reciprocal, we introduced something. Did you see it? I gave you a hint in my example with z and w.
