What type of pair is formed by the equations (14x+5y=44) and (7x+3y=23)?

Answer and explanation

Correct answer: Consistent and independent

For the two equations, \(\frac{a_1}{a_2}=\frac{14}{7}=2\) and \(\frac{b_1}{b_2}=\frac{5}{3}\). Since \(\frac{a_1}{a_2}\ne\frac{b_1}{b_2}\), the two lines intersect at exactly one point, so the pair has a unique solution. Therefore, it is consistent and independent. In a consistent dependent pair, all three corresponding ratios are equal. Exam tip: first compare the ratios of the coefficients of \(x\) and \(y\).
