The equation is

          (Add 5 to each side)

                      (Apply Additive inverse property: 5 – 5 = 0)

                           (Add:  5 + 19 = 24)

Check:

To check the solution, substitute    in original equation.

\ \

              (Subtract: 24-5=19)

The statement is true.

          to graph the solution on the number line;

\
•        draw the number line
\
•       mark a dot at 24 on the number line
\

The value of g=24.
