-3=3-y

You want the unknowns on one side and everything else on the other side. Let's move the 3 on the right side to the left side. We can do that by adding -3 to both sides.

-3+(-3)=3+(-3)-y

Remove the parentheses.

-3-3=3-3-y

Now combine terms.

-6=-y

Now multiply both sides by -1 to get rid of the minus signs (we want to know y, not -y).

-1*-6=-1*-y

6=y or if you prefer

y=6

check my work.
