Substitute for either x or for y according to the first ratio equation.

x%2Fy=1%2F2
x=y%2F2



%282x%2B3y%29%2F%28x%2B4y%29

the substitution, %282%28y%2F2%29%2B3y%29%2F%28%28y%2F2%29%2B4y%29

%28y%2B3y%29%2F%28y%2F2%2B4y%29

4y%2F%28y%2F2%2B4y%29

%28y%2Fy%29%284%2F%281%2F2%2B4%29%29

4%2F%281%2F2%2B4%29

%284%2F%281%2F2%2B4%29%29%282%2F2%29

8%2F%282%281%2F2%2B4%29%29
