By solving system by elimination, x= -1 and y=3
Step-by-step explanation:
We need to solve the systems by elimination.
![12x+9y=15\,\,\,(1)\\3x+2y=3\,\,\,(2)](https://tex.z-dn.net/?f=12x%2B9y%3D15%5C%2C%5C%2C%5C%2C%281%29%5C%5C3x%2B2y%3D3%5C%2C%5C%2C%5C%2C%282%29)
Multiply eq(2) with 4 and subtract eq (1) and eq(2)
![12x+9y=15\,\,\,(1)\\12x+8y=12\,\,\,(2)\\-\,\,\,\,-\,\,\,\,\,\,\,\,\,\,\,-\\--------\\y=3](https://tex.z-dn.net/?f=12x%2B9y%3D15%5C%2C%5C%2C%5C%2C%281%29%5C%5C12x%2B8y%3D12%5C%2C%5C%2C%5C%2C%282%29%5C%5C-%5C%2C%5C%2C%5C%2C%5C%2C-%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C-%5C%5C--------%5C%5Cy%3D3)
Now, multiply eq(1) with 2 and eq(2) with 9 and subtracting both equations:
![24x+18y=30\\27x+18y=27\\-\,\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,-\\-------\\-3x=3\\x=\frac{3}{-3}\\ x=-1](https://tex.z-dn.net/?f=24x%2B18y%3D30%5C%5C27x%2B18y%3D27%5C%5C-%5C%2C%5C%2C%5C%2C%5C%2C-%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C%5C%2C-%5C%5C-------%5C%5C-3x%3D3%5C%5Cx%3D%5Cfrac%7B3%7D%7B-3%7D%5C%5C%20x%3D-1)
So, by solving system by elimination, x= -1 and y=3
