Answer:
<h3>The given system of equations
and</h3><h3>
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>
______________
<h3>Therefore the value of is y=-6</h3><h3>Substitute the value of y in equation (1) we have</h3>
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
and</h3><h3>
has exactly one solutione given system of equations has exactly one solution</h3>
