2 sentences contain the information we are after.

The first, [The sum of the 2 numbers is 15], we learn that:

There are 2 numbers we are looking for, as we don't know what they are, we will refer to them as $$x$$ and $$y$$.

The sum of $$x$$ and $$y$$ is 15. This can be mathematically expressed as $$x+y=15$$

A partir de la siguiente oración, [the quotient of the 2 numbers is 4], aprendemos que la quotient de $$x$$ y $$y$$ es igual a 4.

Esta información puede entonces ser expresada en otra ecuación, que sería $$\frac{x}{y}=4$$

Ahora tenemos un sistema de ecuaciones:

$$x+y=15$$
$$\frac{x}{y}=4$$
