Answer:
x=5 y =-6
Step-by-step explanation:
- 8x-10y=20
-8x - 6y=-4
Multiply the first equation by -1
8x +10y=-20
Add this to the second equation
8x +10y=-20
-8x - 6y=-4
------------------
4y = -24
Divide each side by 4
4y/4 = -24/4
y = -6
Now we need to solve for x
8x +10(-6) = -20
8x -60 = -20
Add 60 to each side
8x -60+60 = -20+60
8x = 40
Divide each side by 8
8x/8 = 40/8
x =5
