Which question are you asking about?
Step-by-step explanation:
Given.
![3x+5y=3](https://tex.z-dn.net/?f=3x%2B5y%3D3)
![x+2y=0](https://tex.z-dn.net/?f=x%2B2y%3D0)
Take the second equation and subtract 2y to both sides.
![(x+2y)-2y=0-2y](https://tex.z-dn.net/?f=%28x%2B2y%29-2y%3D0-2y)
![x=-2y](https://tex.z-dn.net/?f=x%3D-2y)
Substitute x into the first equation and simplify.
![3x+5y=3](https://tex.z-dn.net/?f=3x%2B5y%3D3)
![3(-2y)+5y=3](https://tex.z-dn.net/?f=3%28-2y%29%2B5y%3D3)
![-6y+5y=3](https://tex.z-dn.net/?f=-6y%2B5y%3D3)
![-y=3](https://tex.z-dn.net/?f=-y%3D3)
Invert.
![y=-3](https://tex.z-dn.net/?f=y%3D-3)
Substitute Y into your second equation.
![x+2y=0](https://tex.z-dn.net/?f=x%2B2y%3D0)
![x+2(-3)=0](https://tex.z-dn.net/?f=x%2B2%28-3%29%3D0)
![x-6=0](https://tex.z-dn.net/?f=x-6%3D0)
Add -6 to both sides.
![(x-6)+6=0+6](https://tex.z-dn.net/?f=%28x-6%29%2B6%3D0%2B6)
![x=6](https://tex.z-dn.net/?f=x%3D6)
Answer:
(6, -3)
Answer:
right triangle
Step-by-step explanation:
Y=3x+4
x=-2
3 (-2)+4= -6+4=-2
x,y=-2,-2
