Solve each of the following inequalities. Represent the solutions algebraically (with symbols) and graphically (on a number line).  

Solve each inequality like you would solve any equation.
Solve for the variable by isolating the variables and number values.


    Note: Steps 1 and 2 can happen in any order.

    Use this simplified inequality to graph the inequality on a number line.
    Then try part (b) using the same strategy.
