Question 910588
work the problem. 
"and" compound inequality
-1 &#8804; 3 + 2x < 11
Subtract 3 along the line to get:
-4 <= 2x < 8
Divide by 2 along the line to get:
-2 <= x < 4
================================ 

"or" compound inequality 
1 – x &#8805; -3 or 5x – 1 > 19
-x >= -4 or 5x > 20
----
Note Dividing by a negative reverses the inequality::
x <= 4 or x > 5
======================
