The first equation tells you that
. If you substitute this expression for
in the second, we have
![2x-(x+3)=-1 \iff x-3=-1 \iff x=2](https://tex.z-dn.net/?f=2x-%28x%2B3%29%3D-1%20%5Ciff%20x-3%3D-1%20%5Ciff%20x%3D2)
And we can deduce ![y=x+3=2+3=5](https://tex.z-dn.net/?f=y%3Dx%2B3%3D2%2B3%3D5)
Step-by-step explanation:
(x+7)(x+4)
x = -4 and -7
