Solve for x and y the following system of equations:


 (CBSE 2008, 2009)

Given pair of linear equations is


…(i)


And …(ii)


On multiplying Eq. (i) by 3 to make the coefficients equal of second term, we get the equation as


…(iii)


On adding Eq. (ii) and Eq. (iii), we get





⇒ x – 1 = 3


⇒ x = 3 + 1


⇒ x = 4


On putting the value of x = 4 in Eq. (ii), we get






⇒ (y – 2) = 3


⇒ y = 3 + 2


⇒ y = 5


Hence, x = 4 and y = 5 , which is the required solution.
