Let first consider the equations one by one and will be solving one by one ;
Multiplying both sides by y will lead ;
Now, consider the second equation which is ;
Multiplying both sides by x will yield
As LHS of both equations (i) and (ii) are same, so equating both will yield;
Multiplying both sides by 4 will yield
Dividing both sides by y will yield :
<em>Hence, the required answer is 16</em>
