For two numbers, the equations (6x+5y=49) and (3x-2y=7) are formed. What will be the solution status?

Answer and explanation

Correct answer: One unique solution

For the given equations, a₁/a₂ = 6/3 = 2 and b₁/b₂ = 5/(-2) = -5/2. Since a₁/a₂ ≠ b₁/b₂, the two lines intersect at exactly one point, so the pair has a unique solution. Infinitely many solutions would require a₁/a₂ = b₁/b₂ = c₁/c₂, which is not true here. Exam tip: first compare the ratios of the coefficients of x and y.
