Now we can solve it by any method, i.e., by substitution, by elimination or by cross multiplication method. We generally use elimination method

 

Multiply (3) by 5 and (4) by 2 we get

 

Now put this value of v = 3 in equation (4) we get

We assumed that  so 

Similarly, we have, so

Hence begin mathsize 12px style straight x equals 1 half space and space straight y equals 1 third end style the required solution of the given basic of equations.
