{2x-5>0⇒2x>5⇒x>2,5
{2x-5<2⇒2x<7⇒x<3,5
x∈(2,5;3,5)

$log_{\frac{1}{2}}(2x-5)\ \textgreater \ -1\ \textless \ =\ \textgreater \ log_{\frac{1}{2}}(2x-5)\ \textgreater \ log_{\frac{1}{2}}2$

ОДЗ:
$2x-5\ \textgreater \ 0\\2x-5\ \textless \ 2$

$2\ \textgreater \ 2x-5\ \textgreater \ 0\\7\ \textgreater \ 2x\ \textgreater \ 5\\3,5\ \textgreater \ x\ \textgreater \ 2,5$
