$$\mathrm{If}\:\mathrm{CD}\:\mid\mid\:\mathrm{AB}\:\mathrm{then} \\ $$$$\frac{\mathrm{AB}}{\mathrm{CD}}\:=\:\frac{\mathrm{BE}}{\mathrm{DE}} \\ $$$$\Rightarrow\:\frac{\mathrm{5}{x}\:−\:\mathrm{6}}{\mathrm{3}{x}}\:=\:\frac{\mathrm{8}\:+\:\mathrm{18}}{\mathrm{18}} \\ $$$$\Rightarrow\:\frac{\mathrm{5}{x}\:−\:\mathrm{6}}{\mathrm{3}{x}}\:=\:\frac{\mathrm{26}}{\mathrm{18}}\:=\:\frac{\mathrm{13}}{\mathrm{9}} \\ $$$$\Rightarrow\:\mathrm{45}{x}\:−\:\mathrm{54}\:=\:\mathrm{39}{x} \\ $$$$\Rightarrow\:\mathrm{6}{x}\:=\:\mathrm{54}\:\Rightarrow\:{x}\:=\:\mathrm{9}\: \\ $$ | ||
