When finding the solution for an equation we get one answer for x. (There is only one number that satisfies the equation.) For 3x – 5 = 16, the only solution is x = 7. When we have an inequality to solve (greater than, less than, greater than or equal to, or less than or equal to) we have a range of numbers that can be a solution.

A linear inequality in two variables is the same as a linear equation in two variables, but instead of an equal sign there is an inequality symbol ((, (, (, or (). Ax + By ( C A, B & C are constants. A & B not both zero. x & y are variables
