Question

Solve by crossmultiplication : x(a-b+ab/a-b)=y(a+b-ab/a+b)and x+y=2a^2

Answer 1

This eq. is solved by cross multiplication method....
Here,
a1=((a-b)+ab/a-b)
b2= - ((a+b)+ab/a+b)
c1= 0
a2= 1
b2= 1
c2= -2a^2
---------------------------------------------------------------------------------------------
x= (a^3-b^3)/a

y= (a^3+b^3)/a
------------------------------------------------------------------------------------------------
Hope this will help you....
