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 create a number line similar to problem 4-68.
Now try part (b) using the same strategy.
