Answer:
![x=4\\\\y=-1](https://tex.z-dn.net/?f=x%3D4%5C%5C%5C%5Cy%3D-1)
Step-by-step explanation:
Given Equation:
Equation:1
Equation:2
Dividing Equation:2 by '3' both the sides:
or
Equation:3
Putting the vale of 'x' in Equation:1
![x-3y=7](https://tex.z-dn.net/?f=x-3y%3D7)
![(3-y)-3y=7\\\\3-y-3y=7\\\\3-4y=7\\\\](https://tex.z-dn.net/?f=%283-y%29-3y%3D7%5C%5C%5C%5C3-y-3y%3D7%5C%5C%5C%5C3-4y%3D7%5C%5C%5C%5C)
Subtracting '3' both sides
![-4y=7-3\\\\-4y=4](https://tex.z-dn.net/?f=-4y%3D7-3%5C%5C%5C%5C-4y%3D4)
![y=\frac{4}{-4}](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B4%7D%7B-4%7D)
![y=-1](https://tex.z-dn.net/?f=y%3D-1)
Putting value of 'y' in Equation:3
![x=3-y](https://tex.z-dn.net/?f=x%3D3-y)
![x=3-(-1)\\\\x=3+1\\\\x=4](https://tex.z-dn.net/?f=x%3D3-%28-1%29%5C%5C%5C%5Cx%3D3%2B1%5C%5C%5C%5Cx%3D4)
The solution of the equations is :
![x=4\\\\y=-1](https://tex.z-dn.net/?f=x%3D4%5C%5C%5C%5Cy%3D-1)
