X + y = 20---- 1
x - y = 8----- 2
From 1+2
2x = 28
x = 14
Substitute x in eq.2
14 -y = 8
y = 6
Ans : x= 14 , y= 6

Answer: Bottom left corner (southwest corner)</h3>

The left endpoint is x = 4, but we don't include this endpoint because of the open hole. We use a parenthesis to indicate "don't include the endpoint"

The interval from 4 to infinity is written as
which is like saying 
Answer:
Hello!
Step-by-step explanation:
