To solve the inequality:
Step 1: Eliminate the Fraction
Multiply both sides of the inequality by 2 to eliminate the
:
Step 2: Combine Like Terms
Bring all
-terms to one side and constant terms to the other side:
Simplify the left side:
Simplify the right side:
So the inequality becomes:
Step 3: Solve for
Divide both sides by
. Remember, dividing by a negative number reverses the inequality sign:

To solve the inequality
, we first simplify the left side:
- Multiply out the left-hand side:
Now the inequality becomes:
-
Rearranging gives:
-
Divide both sides by -1 (which flips the inequality):
Thus, we conclude that:
.
Now, for further options:
- Since
means we’re looking at numbers less than this value, it’s important to remember that as increases towards , it approaches but never touches it. - The boundary point
itself is not included in the solution set, forming an open interval in the negative number system.
