Verified answer

Respuesta:

[tex] \frac{x}{y} = \frac{3}{7} \\ x = \frac{3y}{7} [/tex]

[tex]x + y = 200 \\ x = 200 - y[/tex]

[tex] \frac{3y}{7} = 200 - y \\ 3y = 7(200 - y) \\ 3y = 1400 - 7y \\ 10y = 1400 \\ y = \frac{1400}{10} \\ y = 140[/tex]

[tex]x = 200 - 140 \\ x = 60[/tex]

HALLAR: Y - X

[tex]140 - 60 = 80[/tex]

Es 80
