Q1 of 186 Page 4

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

2x + 3y = 46


3x + 5y = 74

Given, pair of equations is


2x + 3y – 46 = 0 and 3x + 5y – 74 = 0


By cross - multiplication method, we have





On taking I and III ratio, we get



⇒ x = 8


On taking II and III ratio, we get



⇒ y = 10
