Can you please check to see if these are right? We have to set each of them to y. Thank You.

x-y=-3: y=-3x

2x+y=5: y=5-2x

2x+y=8: y=8-2x

• Math -

First one is wrong

x-y=-3
-y = -x - 3
y = x + 3

• Math -

(A) y =x+3
(B) correct
(C) correct

Can someone please check this to see if I have reduced to simplest terms: {(-x-y)X(x-y)}/{(x-y)^2 + (x+y)^2} I get -1/2 (x-y)(x+y)divided by (x^2+y^2). Is this right and if so, can it be simplified any more?
