Ответ:

Step-by-step explanation:
If I remember this math correctly if the < doesn’t have a line under it the circle is open. If it does the circle is a closed circle. Since it’s less than -27 that means it’s probably more negative than that. If that’s wrong sorry =(
Ответ:
Plug in x-1 to the first equation and solve.
-4x+3(x-1)=-2
-4x+3x-3=-2
-x=1
X=-1
You then plug x into one of the original equations and solve
Y=-1-1
Y=-2
(-1,-2)
