Próxima vez, em inglês por favor.



The difference between two numbers is 15.

$x-y=15$

Multiplying the largest by 11, the difference becomes 535.

$\displaystyle 11x - y = 535$

Calculate the two numbers.

$10x = 520 \implies x = 52 \implies y = 37$

Sheesh. Am I the only one around here that doesn't speak Portuguese/Spanish?
