Solve the system of equations. - 9Y + 4X - 20 = 0

-7Y + 16 X - 80 = 0

X=

Y=

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

-7Y+16X-80=0

2. We can subtract these two equations.

-36Y + 16X - 80 = 0

-7Y+16X-80=0

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

X=5, Y=0
