The downloaded data for x standard version is 2.7x and for y high quality version is 4.2y. The total downloaded data is 3219. So,

2.7x+4.2y=3219

Substitute 2x for y in the equation and solve the obtained equation for x.

\begin{gathered} 2.7x+4.2\cdot2x=3219 \\ 2.7x+8.4x=3219 \\ x=\frac{3219}{11.1} \\ =290 \end{gathered}

So value of x is 290. Thus downloads of the standard version were 290.

Answer: 290
