Given : a₁x + b₁y + c₁= 0 and a₂x + b₂y + c₂ = 0,
To Find : Condition for followings
(a) अद्वितीय हल होगा
(c) अनंततः अनेक हल होंगे
(b) कोई भी हल नहीं होगा
Solution:
The general form for a pair of linear equations in two variables x and y is
a₁x + b₁y + c₁= 0 and
a₂x + b₂y + c₂ = 0,
Where a₁, b₁, c₁, a₂ , b₂, c₂ are all real numbers and a₁² + b₁² ≠ 0, a₂² + b₂² ≠ 0
a₁/a₂ = b₁/b₂ = c₁/c₂ Infinite solution ( same line)
अनंततः अनेक हल होंगे
a₁/a₂ = b₁/b₂ ≠c₁/c₂ No solution ( parallel lines)
कोई भी हल नहीं होगा
a₁/a₂ ≠ b₁/b₂ Unique solution ( intersecting lines)
अद्वितीय हल होगा
