\[6x 4y=12\] \[y=\frac{3}{2}x3\] \[m_{N}=\frac{2}{3}\] \[m_{N}=\frac{2}{k}\] Therefore k=3

\[x2y=6[1]\] \[3xy=2[2]\] \[[1]\times 3\] \[3(x2y)=3(6)\] \[3x6y=18[3]\] \[[2][3]\] \[(3xy)(3x6y)=(2)(18)\] \[5y=20\] \[y=4\] Substitute the yvalue (ie. 4) into any of the three equations above (ie. [1], [2], [3]) to find the xvalue.

You don't need anyone's help with that. Just read the wiki page. It shows you what to add and subtract.
