Solve the following pairs of equations


Given pair of linear equations is

…(i)


and …(ii)


Let and then the above equations become:



…(iii)


and


…(iv)


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.
