Q1 of 40 Page 98

Solve each of the following pairs of equations by reducing them to a pair of linear equation.


6x + 3y = 6xy

2x + 4y = 5xy


⇒ ….I


⇒ ….II


Let = p and = q


6p + 3q = 6


2p + 4q = 5


Multiplying eq. IV by 3 and subtracting from Eq. III


6p + 3q = 6


6p + 12q = 15


-9q = -9


q = 1


substitute the value of q in III


6p + 3(1) = 6


p =


But, ⇒ x = 2


⇒ y = -1
