Two Step Inequalities

Solving Two Step Inequalities

The variable must be alone or isolated on one side of the inequality.
Isolate the variable by using inverse or opposite operations.
Whatever you do to one side you must do to the other.

Two Step Inequalities

Solving Two Step Inequalities

When you multiply or divide BY a negative number, the inequality sign is flipped.

Multiple Choice

True or False:

10 + 3k < 22

Answers in the solution set will be negative

True

False

Solution has the < or the > sign.
The number in the solution will be included in the solution set.
