Explanation:

First, subtract  

3

from each segment of the system of inequalities to isolate the  

x

term while keeping the system balanced:

to solve for  

x

while keeping the system balanced. However, because we are multiplying or dividing inequalities by a negative number we must reverse the inequality operators:

Answer:

x [tex]\geq[/tex] -1

Step-by-step explanation:

First, we divide each side by -3. Since the number that we are dividing by is negative we have to flip our inequality symbol.

I hope this helps!
