5 times 325=5x-y should be the equation.
Answer:
<h3>The given system of equations
![y=-8x-6](https://tex.z-dn.net/?f=y%3D-8x-6)
and</h3><h3>
![y=8x-6](https://tex.z-dn.net/?f=y%3D8x-6)
has exactly one solution</h3>
Step-by-step explanation:
Given that the system of equations
and
has exactly one solution
<h3>For :</h3><h3>Now to show that the given system of equations has exactly one solution :</h3><h3>Solving the given equations (1) and (2) to get solution</h3><h3>Adding the equations (1) and (2) we get</h3>
![y=-8x-6](https://tex.z-dn.net/?f=y%3D-8x-6)
______________
![2y=0-12](https://tex.z-dn.net/?f=2y%3D0-12)
![y=-\frac{12}{2}](https://tex.z-dn.net/?f=y%3D-%5Cfrac%7B12%7D%7B2%7D)
![=-6](https://tex.z-dn.net/?f=%3D-6)
<h3>Therefore the value of is y=-6</h3><h3>Substitute the value of y in equation (1) we have</h3>
![-6=-8x-6](https://tex.z-dn.net/?f=-6%3D-8x-6)
![-8x-6+6=0](https://tex.z-dn.net/?f=-8x-6%2B6%3D0)
![-8x+0=0](https://tex.z-dn.net/?f=-8x%2B0%3D0)
![-8x=0](https://tex.z-dn.net/?f=-8x%3D0)
![x=-\frac{0}{8}](https://tex.z-dn.net/?f=x%3D-%5Cfrac%7B0%7D%7B8%7D)
![=0](https://tex.z-dn.net/?f=%3D0)
Therefore the value of x is x=0
<h3>Therefore it has exactly one solution is (0,-6)</h3><h3>Therefore the given system of equations
![y=-8x-6](https://tex.z-dn.net/?f=y%3D-8x-6)
and</h3><h3>
![y=8x-6](https://tex.z-dn.net/?f=y%3D8x-6)
has exactly one solutione given system of equations has exactly one solution</h3>
