One solution let's find that

$\\ \rm\hookrightarrow 7x=5x-25+30$

$\\ \rm\hookrightarrow 7x=5x+5$

$\\ \rm\hookrightarrow 2x=5$

$\\ \rm\hookrightarrow x=5/2$

$\\ \sf\longmapsto \dfrac{3}{x-4}=\dfrac{6}{x-5}$

$\\ \sf\longmapsto 3(x-5)=6(x-4)$

$\\ \sf\longmapsto 3x-15=6x-24$

$\\ \sf\longmapsto 3x-6x=-24+15$

$\\ \sf\longmapsto -3x=-9$

$\\ \sf\longmapsto x=\dfrac{-9}{-3}$

$\\ \sf\longmapsto x=3$

$\\ \sf\longmapsto KM=3+6=9$
