The equation is *x* + 14 = 25.

Apply subtraction property of equality: Subtract 14 from each side.

*x* + 14 * *14 = 25 * 14*

*x* + 0= 25 * 14 (Apply additive inverse property: 14**14** *= 0)

*x* = 25 * 14 (Apply additive identity property: **x* + 0 = *x*)

*x* = 11 (Subtract: 25*14 =** *11)

__Check:__

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

x + 14 = 25* *11 + 14 = 15

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

The statement is true.

Graph the solution on number line.

- First draw a number line.
- Mark a dot at 11 on the number line.

The value of * x *= 11.
