(x/(8−x))×(6/4)×(4/2)=1  ⇒x=2  (x/(8−x))×(6/4)×((6+y)/y)=1  ⇒y=6  PS=2+y=8 ✓
$$\frac{{x}}{\mathrm{8}−{x}}×\frac{\mathrm{6}}{\mathrm{4}}×\frac{\mathrm{4}}{\mathrm{2}}=\mathrm{1} \\ $$$$\Rightarrow{x}=\mathrm{2} \\ $$$$\frac{{x}}{\mathrm{8}−{x}}×\frac{\mathrm{6}}{\mathrm{4}}×\frac{\mathrm{6}+{y}}{{y}}=\mathrm{1} \\ $$$$\Rightarrow{y}=\mathrm{6} \\ $$$${PS}=\mathrm{2}+{y}=\mathrm{8}\:\checkmark \\ $$
