x=((2m)/3)  y=((2n)/3)   z=((2k)/3)  ((4m)/3)+2n+((2k)/3)=22  4m+6n+2k=66  4(13−k)+6n+2k=66  6n−2k=66−52=14  3n−k=7
$${x}=\frac{\mathrm{2}{m}}{\mathrm{3}}\:\:{y}=\frac{\mathrm{2}{n}}{\mathrm{3}}\:\:\:{z}=\frac{\mathrm{2}{k}}{\mathrm{3}} \\ $$$$\frac{\mathrm{4}{m}}{\mathrm{3}}+\mathrm{2}{n}+\frac{\mathrm{2}{k}}{\mathrm{3}}=\mathrm{22} \\ $$$$\mathrm{4}{m}+\mathrm{6}{n}+\mathrm{2}{k}=\mathrm{66} \\ $$$$\mathrm{4}\left(\mathrm{13}−{k}\right)+\mathrm{6}{n}+\mathrm{2}{k}=\mathrm{66} \\ $$$$\mathrm{6}{n}−\mathrm{2}{k}=\mathrm{66}−\mathrm{52}=\mathrm{14} \\ $$$$\mathrm{3}{n}−{k}=\mathrm{7} \\ $$
