The equation is

               (Add 4 to each side)

                              (Apply Additive inverse property: 4-4 = 0)

                                        (Add:  )

Check:

To check the solution, substitute in original equation.

                                       (Subtract: -4-4=--8)

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
\
