Then go through it step by step.

You want to solve \(\displaystyle -1= \frac{8- 5}{y- 3}\). What is the first thing you would do?

8-5 =3
y-3=3
If you don't know what y is, how do you know that y- 3= 3? Are you saying that y= 6? Why?

3 divide 3 = 1
So this is obviously wrong because it is supposed to be -1!

Solve \(\displaystyle \frac{3}{y- 3}= -1\)
What would be your first step.
