The equation is .

Apply addition property of equality: Add 14 to each side.

                                     (Apply additive inverse property: )

                                   (Apply additive identity property: )

Check:

To check the solution, substitute y = 39 in original equation. \ \

25 =25                               (Subtract: 39 – 14 = 25)

The statement is true.

To graph the solution on the number line:

\
• First draw the number line
\
• Mark a dot at 39 on the number line
\

The value of .
