Example:

-2(x-y) Y=-3. Do I change the equation to -2(x+3y), because of the minus sign or do I make it -2(x-(-3y))?

Actually, neither of thoise would be correct. As you typed the equation, it looks like this:

-2(x-y)y= -3

Please correct me if I misinterpreted your question.

if you multiply the -2 through, you get:

[-2x-(-2y)]y = -3

Remembering that a negative times a negative is a positive number:

[-2x+2y]y = -3

Hope this helps.

I am distributing Y=3 is not in the equation. It's
-2(x-y)

But y=-3, so with the minus sign I am confused when I plug the -3 in. Do I make it a positive three because to the two negatives rule, or do I live it -3?

If y=-3, you have

If y=-3, you have

Thanks, this was giving me a lot of problems.
