What type of pair is formed by the equations (22x+33y=99) and (2x+3y=11)?

Answer and explanation

Correct answer: Inconsistent

Compare the corresponding coefficients: \(\frac{22}{2}=11\) and \(\frac{33}{3}=11\), but \(\frac{99}{11}=9\). Thus, \(\frac{a_1}{a_2}=\frac{b_1}{b_2}\neq\frac{c_1}{c_2}\), which is the condition for an inconsistent pair. The two lines are distinct and parallel, so the equations have no solution. Exam tip: compare \(a_1/a_2\), \(b_1/b_2\), and \(c_1/c_2\); the pair is dependent only when all three ratios are equal.
