Question

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

$$\begin{gathered} bx+cy=a+b \\ ax\left(\frac{1}{a-b}-\frac{1}{a+b}\right)+cy\left(\frac{1}{b-a}-\frac{1}{b+a}\right)=\frac{2a}{a+b} \end{gathered}$$

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

Now for y

Hence we get the value of and
