Answer:
There is one solution (-4,-4)
Explanation:
5x + 5 y = -40 → multiply by 2 10x + 10y = -80
-10x + 2y = 32 -10x + 2y = 32
12y = -48 Divide by 12
12y = -48
y = -4
To solve for x, substitute -4 for y into either of the two original equations.
5x + 5y = -40
5x + 5(-4) = -40
5x - 20 = -40 Add 20 to both sides
5x = -20 Divide both sides by 5
x = -4
(-4,-4)
