The equation is x + 14 = 25.

\

x + 14 \"\" 14 = 25 \"\" 14               (Subtract 14 from each side)

\

x = 25 \"\" 14                               (Apply Additive inverse property: 5 \"\" 5 = 0)

\

x = 11                                        (Subtract: 33 \"\" 5 = 28)

Check:

\

To check the solution, substitute = 11 in original equation.

\

x + 14 = 25\"\" 11 + 14 = 15

\

25 = 25                               (Add: 11 + 14 = 25)

\

The statement is true.
