Question

x/7 + x/5 = 24
ayuda

Answer 1

¡Hola!

$\frac{x}{7} + \frac{x}{5} = 24 \\ \\ \frac{5x + 7x}{35} = 24 \\ \\ 12x = 24 \times 35 \\ \\ x = \frac{840}{12} \\ \\ \boxed{x = 70}$

Vamos a comprobar...

$\frac{x}{7} + \frac{x}{5} = 24 \\ \\ \frac{70}{7} + \frac{70}{5} = 24 \\ \\ 10 + 14 = 24 \\ \\ 24 = 24$

Espero que sirva y saludos.
