I am in dire need of assistance. Can anyone tell me the forumula/solution to transforming inqualities into equivalent inequalities with y alone on one side? I really don't understand this.

We can work with specific examples much better than not. If you have specific inequaliaties that are troubling you , post them, or a sample of them.
Oh, okay. Well, I've seen this before:
2x + 3y > 0
2x + 3y > 0
You handle it like an alg problem.
subtract 2x from each side.
3y>-2x
divide by 3
y>-2/3 x
that is it. Only one thing you have to be worried about, if you multiply or divide by a negative number, the inequality changes: example
2x-3y>15
-3y>15-2x
and here we divide by -3, watch the inequality sign reverse...
y<-5+2/3 x
subtract 2x from each side.
3y>-2x
divide by 3
y>-2/3 x
that is it. Only one thing you have to be worried about, if you multiply or divide by a negative number, the inequality changes: example
2x-3y>15
-3y>15-2x

y<-5+2/3 x
