Answer:
![x=3](https://tex.z-dn.net/?f=x%3D3)
![y=-4](https://tex.z-dn.net/?f=y%3D-4)
Step-by-step explanation:
----------- (1)
-----------(2)
Adding equation (1) and (2)
![4x+5y-4x-4y=-8+4](https://tex.z-dn.net/?f=4x%2B5y-4x-4y%3D-8%2B4)
![y=-4](https://tex.z-dn.net/?f=y%3D-4)
Substitute y=-4 in equation (1) or (2)
![4x+5(-4)=-8](https://tex.z-dn.net/?f=4x%2B5%28-4%29%3D-8)
![4x-20=-8\\4x=-8+20\\4x=12\\x=3](https://tex.z-dn.net/?f=4x-20%3D-8%5C%5C4x%3D-8%2B20%5C%5C4x%3D12%5C%5Cx%3D3)
