Q1 of 186 Page 4

Solve the following pair of linear equation by cross - multiplication method:


Given, pair of equations is




Let uand v


So, Eq. (1) and (2) reduces to


2u + 3v – 13 = 0


5u – 4v + 2 = 0


By cross - multiplication method, we have





On taking I and III ratio, we get



⇒ u = 2


On taking II and III ratio, we get



⇒ v = 3


So, u


and v
