$\frac{ \times }{2} + 9$
⬆️este va arriba
=17 ​

Answer 1

$\frac{x}{2} + 9 = 17 \\ \\ \frac{x}{2} = 17 - 9 \\ \frac{x}{2} = 8 \\ x = 8 \times 2 \\ x = 16 \\ comprobacion = \\ \frac{x}{2} + 9 = 17 \\ \frac{16}{2} + 9 = 17 \\ 8 + 9 = 17 \\ 17 = 17$

Answer 2

- Ecuación:

❀ Resolvemos la ecuación:

$\frac{x}{2} + 9 = 17 \\ \\ \frac{x}{2} = 17 - 9 \\ \\ \frac{x}{2} = 8 \\ \\ x = 8 \times 2 \\ \\ x = 16$

El número es 16.

❀ Comprobamos:

$\frac{x}{2} + 9 = 17 \\ \\ \frac{16}{2} + 9 = 17 \\ \\ 8 + 9 = 17 \\ \\ 17 = 17$
