What is the correct solution status for the equations (29x+12y=101) and (14x+6y=49)?

Answer and explanation

Correct answer: One unique solution

Here, \\(\frac{29}{14} \ne \frac{12}{6}\\). Therefore, the two lines intersect at exactly one point, so the pair of equations has a unique solution. In fact, multiplying the second equation by 2 and subtracting it from the first gives \(x=3\), followed by \(y=\frac{7}{6}\). Thus, the solution is unique but not an integer, so option D is incorrect. Exam tip: If \(\frac{a_1}{a_2} \ne \frac{b_1}{b_2}\), a pair of linear equations always has a unique solution.
