What is the correct conclusion by observing (12x-8y=20) and (3x-2y=6)?

Answer and explanation

Correct answer: No solution

Here, a₁/a₂ = 12/3 = 4 and b₁/b₂ = (−8)/(−2) = 4, whereas c₁/c₂ = 20/6 = 10/3. Thus, a₁/a₂ = b₁/b₂ ≠ c₁/c₂. The two lines are parallel and distinct, so they have no common point or solution. Exam tip: If a₁/a₂ = b₁/b₂ ≠ c₁/c₂, a pair of linear equations has no solution.
