Answer:

x = -3 and y = 2

Explanation:

Since y = x + 5 and y = -2x - 4, so we can go ahead and equate the equal parts and solve for x;

[tex]\begin{gathered} x+5=-2x-4 \\ x+2x=-5-4 \\ 3x=-9 \\ x=-\frac{9}{3} \\ \therefore x=-3 \end{gathered}[/tex]

So x = -3, we can go ahead and substitute the value of x into the 1st equation to determine the value of y;

[tex]\begin{gathered} y=x+5 \\ y=-3+5 \\ \therefore y=2 \end{gathered}[/tex]

So x = -3 and y = 2
