Respuesta:
[tex] \frac{2x}{5} = 16 \\ 2x = 16 \times 5 \\ 2x = 80 \\ x = 40[/tex]
Explicación paso a paso:
[tex] \frac{x}{9} + 64 = 100 \\ \frac{x}{9} = 100 - 64 \\ \frac{x}{9} = 36 \\ x = 36 \times 9 \\ x =324[/tex]
[tex] \frac{x}{6} + 7 = 12 \\ \frac{x}{6} = 12 - 7 \\ \frac{x}{6} = 5 \\ x = 5 \times 6 \\ x = 30[/tex]
[tex] \frac{x}{7} = 49 \\ x = 49 \times 7 \\ x = 343[/tex]
