Answer:
<h3>
There is one unique real number solution at (–1, –3)</h3>
Step-by-step explanation:
Given the two linear equation
–4x – 7 = y ...1
x² – 2x – 6 = y ...2
Equating the left hand side of both equations since they are equal to the same variable y will give;
Substituting x=1 into equation 1 we have;
This means there is only one unique real number solution at (-1, -3)
