  • 18-6=12


\\ \sf\longmapsto (6)/(12)=(2x-7-14)/(14)


\\ \sf\longmapsto (6)/(12)=(2x-21)/(14)


\\ \sf\longmapsto 12(2x-21)=72


\\ \sf\longmapsto 2x-21=6


\\ \sf\longmapsto 2x=27

Now


\\ \sf\longmapsto 2x-7=27-7=20

  • 33-9=24


\\ \sf\longmapsto (24)/(9)=(40)/(-x+30)


\\ \sf\longmapsto 24(-x+30)=320


\\ \sf\longmapsto -24x+720=320


\\ \sf\longmapsto -24x=320-720=-400


\\ \sf\longmapsto x=(-400)/(-24)


\\ \sf\longmapsto x=16.6
