Answer:
x = 3 and y = -1
Explanation:
The first equation of the system is:
y = - 3x - 10
The second equation of the system is:
y = -1
The second equation is solved for y, so we can take the second equation and replace the value of y in the first equation as follows:
y = - 3x - 10
-1 = - 3x - 10
Now, we can solve for x, so adding 10 to both sides of the equation, we get:
-1 + 10 = -3x - 10 + 10
9 = - 3x
Dividing by -3 into both sides:
[tex]\begin{gathered} \frac{9}{-3}=\frac{-3x}{-3} \\ -3=x \end{gathered}[/tex]Therefore, the solution of the system is x = -3 and y = -1
