State the correct solution status for (9x+5y=17) and (4x+2y=11).

Answer and explanation

Correct answer: One unique solution

For the two linear equations, \(\frac{a_1}{a_2}=\frac{9}{4}\) and \(\frac{b_1}{b_2}=\frac{5}{2}\). Since \(\frac{9}{4}\ne\frac{5}{2}\), the two lines intersect at exactly one point, so the pair has a unique solution. Therefore, option A is correct. Exam tip: when \(\frac{a_1}{a_2}\ne\frac{b_1}{b_2}\), a pair of linear equations always has a unique solution.
