ABSOLUTE VALUE INEQUALITIES
Just like absolute value equations,
inequalities will have two solutions: |3x -
2| ≤ 7 3x – 2 ≤ 7 +2 +2 3x ≤ 9 x ≤ 3
-5/3 ≤ x ≤ 3[ -5/3, 3 ]
-7 ≤ 3x – 2+2 +2 -5 ≤ 3x -5/3 ≤ x
-7≤ 3x – 2 ≤ 7

Try again:
|2x + 1| < 11
-11 < 2x +1
AND
-12 < 2x
-6 < x
2x +1 < 11

ABSOLUTE VALUE INEQUALITIES
If the sign is less than, the answer is written as
one statement.• |2x + 1| < 11
• -6 < x < 5 (-6, 5)
If the sign is greater than, the answer must be
written as two statements.• See the next problem.
