When we graph inequalities in two variables on the coordinate plane, we do not graph compound inequalities. We move on to solving systems of inequalities. It takes a little from both inequalities with one variable and solving systems graphically. ... Step 1: Step 2: ON THE SAME GRAPH Graph and shade the 1st inequality Graph and shade the 2nd ...

Note: some inequalities have no solution and others are true for all real numbers. Example: Solving Inequalities (Multi-Step) Solve the following inequalities and graph the solution on the number line. 2y + 3 < 9 b. 3y + 2y > 15. Step 1: Opposite of add is subtract Step 1: Add like terms. So subtract 3 from both sides So add 3y + 2y. Step 2

For inequalities without modulus, the first step is to set one side of the inequality to zero and then factorise or complete the square on the other side. When solving inequalities with equal signs, the critical values in the answer must be evaluated first with the original expression to test if the value is applicable as a solution. Let a, b ( (.

Solving Multistep Inequalities 3 – 6 . When solving inequalities that involve more than one operation, work backward to undo the operations, just as when you solve multi-step equations. Remember to reverse the inequality symbol if you multiply or divide each side of an inequality by a negative number, as in example 2. Example 1 Example 2
