The equation is

               (Add 6 to each side)

                          (Apply Additive inverse property: 6 – 6 = 0)

                                  (Add:  -2 + 6 = 4)

Check:

To check the solution, substitute in original equation.

              (Subtract: 4-6=-2)

The statement is true.

          to graph the solution on the number line;

\
•        draw the number line
\
•       mark a dot at 4 on the number line
