For prices of two tickets, the equations (8x+3y=280) and (16x+6y=575) are formed. What type of system is this?

Answer and explanation

Correct answer: Having no solution

The ratios of the coefficients are \(\frac{8}{16}=\frac{3}{6}=\frac{1}{2}\), but the ratio of the constant terms is \(\frac{280}{575}=\frac{56}{115}\neq\frac{1}{2}\). Thus, \(\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq\frac{c_1}{c_2}\), so the two lines are parallel and have no common solution; the system is inconsistent. Option B would be correct only if all three ratios were equal, giving infinitely many solutions. Exam tip: Compare the three coefficient and constant ratios directly to identify the type of system quickly.
