Answer:


\boxed{\sf x=-2}


\boxed{\sf y=-4}

Explanation:

First, Let's solve for x in -2x+2y=-4:


\sf -2x+2y=-4

Subtract 2y from both sides:


\sf -2x+2y-2y=-4-2y


\sf -2x=-4-2y

Divide both sides by -2:


\sf \cfrac{-2x}{-2}=-\cfrac{4}{-2}-\cfrac{2y}{-2}


\bold{ x=y+2}

Now, we'll substitute x=y+2 to 3x+3y=-18:


\sf 3x+3y=-18

→ let x=2+y


\sf 3\bold{(2+y)}+3y=-18

Simplify:


\sf 6+6y=-18

Now, let's solve for y in 6+6y=-18


\sf 6+6y=-18

Subtract 6 from both sides:


\sf 6+6y-6=-18-6


\sf 6y=-24

Divide both sides by 6:


\sf \cfrac{6y}{6}=\cfrac{-24}{6}


\bold{ y=-4}

Now, substitute y=-4 into x=2+y:


\sf x=2+y

→ let y = -4


\sf x=2+\bold{-4}


\bold{x=-2}

Therefore, x=-2 and y=-4.
