General Inequalities and Their Applications

The approach to solving linear inequalities is similar to equations: first, simplify each side, then isolate a variable by doing the same thing to both sides. Remember to switch the sign when multiplying or dividing by a negative number. This lecture series shows examples of solving inequalities and using them to solve word problems. Watch the videos and complete the interactive exercises.

Multi-step linear inequalities - Questions

1. Solve for r.
Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.

35 r-21 < -35 r+19


2. Solve for a.
Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.

60 a+64 \geq 80 a-92


3. Solve for t.
Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.

-48 t+2 \leq-71 t+14


4. Solve for w.
Reduce any fractions to lowest terms. Don't round your answer, and don't use mixed fractions.

53 w+13 < 56 w+16
