Question

Solve each of the following systems of equations by the method of cross-multiplication :

$$\begin{gathered} x\left(a-b+\frac{ab}{a-b}\right)=y\left(a+b-\frac{ab}{a+b}\right) \\ x+y=2a^2 \end{gathered}$$

Answer 1

GIVEN:

To find: The solution of the systems of equation by the method of cross-multiplication:

Here we have the pair of simultaneous equation

By cross multiplication method we get

Consider the following for x

And

Hence we get the value of and
