3. Solving some simple inequalities Suppose we want to solve the inequality x+3 > 2. We can solve this by subtracting 3 from both sides: x+3 > 2 x > −1 So the solution is x > −1. This means that any value of x greater than −1 satisﬁes x+3 > 2. Inequalities can be represented on a number line such as that shown in Figure 1. The solid line

Solving Inequalities! ! Solving inequalities is the same as solving equations. ! There are only 2 things you need to know… ! 1.) If you multiply or divide by a negative number you must switch the sign. -7x < 21 -7 -7 x > -3 ! 2.) You will graph your solutions. Dividing by a negative means switch the sign!!
Multi-step inequalities are solved just like multi-step equations except that you have to be aware of when to reverse the inequality symbol. y ≥ - 3 Notice the symbol only switched when we divided by a negative number. Practice: Solve the following inequalities.
