Solve LINEAR inequalities (Part 1)

Follow us:

The procedure for solving linear inequalities is the same as the procedure for solving linear equations, with one important exception: When multiplying or dividing both sides of the inequality by a negative number, reverse the direction of the inequality symbol, changing the sense of the inequality.

A linear inequality : ax + b ≤ c

Solving an inequality is the process of finding the set of numbers that make an inequality a true statement.

A solution set is the set of all numbers that satisfy the inequality.
