What is the correct conclusion by observing the equations (24x-18y=102) and (4x-3y=18)?

Answer and explanation

Correct answer: No solution

For the two equations, a₁/a₂ = 24/4 = 6 and b₁/b₂ = (-18)/(-3) = 6, but c₁/c₂ = 102/18 = 17/3, which is not 6. Thus, a₁/a₂ = b₁/b₂ ≠ c₁/c₂, so the lines are parallel and distinct and the pair has no solution. Infinitely many solutions would occur only when all three corresponding ratios are equal. Exam tip: compare the ratios of the coefficients first, then compare them with the ratio of the constants.
