The equation is x – 24 = 73.

Apply addition property of equality: Add 24 to each side.

            (Apply additive inverse property: )

                  (Apply additive identity property: )

                          (Add: )

Check:

To check the solution, substitute x = 97 in original equation.

x – 24 = 73 97 – 24 = 73

73 =  73                          (Subtract: 97 – 24= 73)

The statement is true.

To graph the solution on the number line:

\
• First draw the number line
\
• Mark a dot at 97 on the number line
\

The value of x = 97.
