Answer:
X=5, Y=0
Step-by-step explanation:
-9Y +4X -20=0
-7Y+16X-80=0
1. We can multiply the first equation by 4. This will equal to -36Y +16X-80=0.
-36Y +16X -80 =0
2. We can subtract these two equations.
We will get -29Y =0. Y=0.
3. Then we can substitute y into the first equation. -9(0) +4x-20 =0. 4x=20. x=5
