Answer:
(-3,3)
Step-by-step explanation:
10x + 8y = -6
-2x − 8y = -18
Add these two equations together to eliminate y
10x + 8y = -6
-2x − 8y = -18
------------------------
8x = -24
Divide each side by 8
8x/8 = -24/8
x = -3
Now we need to find y
10x + 8y = -6
Substitute x =-3
10 (-3) + 8y = -6
-30 +8y = -6
Add 30 to each side
-30+30 +8y = -6+30
8y = 24
Divide by 8
8y/8 = 24/8
y =3
