Solve the following pairs of equations

Given, pair of linear equations is

On multiplying both sides by LCM (3, 4) = 12, we get

…(i)

and

On multiplying both sides by LCM

(6, 8) = 24, we get

…(ii)

Now, adding Eqs. (i) and (ii), we get

24x = 144

x = 6

Now, put the value of x in Eq. (i), we get

Hence, the required values of x and y are 6 and 8, respectively.
