Document Summary
Unlike equations which usually have a finite number of solutions (or no solution at all), inequalities often have infinitely many solutions. We typically describe the solutions to an inequality in one of three ways: Linear inequalities: graph the solution on a number line, write the solution in set builder notation, write the solution in interval notation. Definition where a, b and c are real numbers and. Note: the inequality symbol < in the definition above and the properties below can be replaced with. A linear inequality is an inequality that can be written in the form ax b c. The technique to use when solving linear inequalities is to isolate the variable on one side. Remember to reverse the direction of the inequality when multiplying or dividing a linear inequality by a negative number. Solve the linear inequality and express the solution in set-builder notation. Use integers or fractions for any numbers in the expression.
