Solve the following system of equations by elimination method:

Given pair of linear equations is

…(i)

And …(ii)

On multiplying Eq. (ii) by to make the coefficients of equal, we get the equation as

…(iii)

On subtracting Eq. (ii) from Eq. (iii), we get

⇒ y = 15

On putting y = 15 in Eq. (ii), we get

⇒ x = 18

Hence, x = 18 and y = 15 , which is the required solution.
