Solving and Graphing Two-Step Inequalities

Let's kick it up another notch. Use what you know about distributing, combining like terms and solving two-step inequalities when solving for x.

7(x + 3) - 5x < 13

• x>-4

• x < 17

• x<-4

• x > -17

Ok. Try this last one.Remember...use what you know about distributing, combining like terms and solving two-step inequalities when solving for x.

-3 − 6(4x + 6) > -111

• x > 3

• x < 3

• x < -3

• x > -3

When do we switch the inequality symbol?

• when multiplying or dividing by a NEGATIVE

• when adding and subtracting a NEGATIVE

• we never switch the inequality

• When there is a negative in the problem
