Answer:
Explanation:
We would like to solve the following system of equations ,
Firstly lets number the equations as ,
Again , we can rewrite the first equation as , equations as ;
Now , substitute the value of equation (iv) in equation (ii) and (iii) .
And ,
Now consider ,
On adding these two equations, we have ;
Now substitute this value in equation (v) ,
Finally substitute the values of a and b in equation (iv) , we have ;
And we are done !
