Notice how the tickets' prices are chosen with whole valued coefficients which could make calculations easier.
<pre>
TYPE       PRICE         QTY.        COST
Premium    3Q             2          3Q*2
Standard   2Q             4          2Q*4
SUM                                  322
</pre>
Form the equation as {{{6Q+8Q=322}}}, 

which easily becomes
{{{14Q=322}}}


{{{highlight_green(Q=23)}}}


From this, Standard Ticket, {{{2Q=highlight(46)}}}
and Premium Ticket, {{{3Q=highlight(69)}}} euros
