What is the correct solution status for (17x+6y=52) and (8x+3y=25)?

Answer and explanation

Correct answer: One unique solution

For two linear equations, a unique solution exists when \\(a_1/a_2 \\ne b_1/b_2\\). Here, \\(17/8 \\ne 6/3\\); equivalently, the determinant is \\(17 \\times 3 - 8 \\times 6 = 3 \\ne 0\\). Therefore, the two lines intersect at exactly one point, so the system has one unique solution. Exam tip: Compare corresponding coefficients in the same order in both equations.
