Solve the following pairs of equations

Given pair of linear equations is


and …(ii)

Let and then the above equations become:




On, multiplying Eq. (iv) by 2 and then adding with Eq. (iii), we get

( + (u - 2v) = (-2 + 32)

5u = 30

Now, put the value of u in Eq. (iv), we get

Hence, the required values of x and y are and respectively.
