solve the following simultaneous equations:

(i) 3/rootx+4/rooty=17/6 ; 5/rootx-6/rooty=1/2

(ii) 2(3x-y)=5xy ; 2(x=3y)=5xy (x is not equal to 0,y is not equal to 0)

Let

So the equations can be re-written as :

Now we multiply equation(1) with 6 and equation (2) with 4 and add resulting equations and we get:

Now to get y we multiply equation(1) with 5 and equation (2) with -3 and add the resulting equations to get:
