Answer:
Which of the following pairs of linear equations has unique solution, no solution, or infinitely many solutions. In case there is a unique solution, find it by using cross multiplication method
(i) x-3y-3=0 3x9y-20
x-3y-3=0 3x - 9y - 2 = 0
x - 3y - 3 = 0
Comparing with a₁x + b₁y+c₁ = 0
a₁ = 1, b₁ = -3, c₁=-3
...(1)
...(2)
3x-9y-2=0
Comparing with a₂x + b₂y + c₂ = 0
a₂ = 3, b₂ = -9, c₂=-2
