100 POINTS! PLEASE HELP!

Semmy [17]

Apply angle bisector theorem

$\\ \sf\longmapsto \dfrac{9}{15}=\dfrac{3}{5}=\dfrac{2x-1}{3x}$

$\\ \sf\longmapsto 9x=5(2x-1)$

$\\ \sf\longmapsto 9x=10x-5$

$\\ \sf\longmapsto 10x-9x=5$

$\\ \sf\longmapsto x=5$

$\\ \sf\longmapsto \dfrac{4}{3}=\dfrac{x}{2.25}$

$\\ \sf\longmapsto 4(2.25)=3x$

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

$\\ \sf\longmapsto x=3$

Hope it helps
