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:
