Question 1123813
Assume that 2 s are the bases of the log, not contained in the expressions.
(If not please resubmit the qustion with the base specified, in case a bare log x can be recognized to be base e or 10)
{{{log(2, x/y)=2, log(2, x-2y)=3}}}
{{{x/y=4}}} 
{{{x-2y=8}}}
{{{4y-2y=8}}}
{{{y=4}}}
{{{x=16}}}
Hope this solves your problem. Thanks!
