Q. 1 C

# Solve the following pair of linear equation by cross - multiplication method:x + 4y + 9 = 05x – 1 = 3y

Given, pair of equations is

x + 4y + 9 = 0 and 5x – 3y – 1 = 0

By cross - multiplication method, we have   On taking I and III ratio, we get x = – 1

On taking II and III ratio, we get y = – 2
