What is the relation among all three ratios in the equations (11x+18y=86) and (33x+54y=258)?

Answer and explanation

Correct answer: All three ratios are equal

The three ratios are \(11/33\), \(18/54\), and \(86/258\). Each ratio equals \(1/3\), so \(11/33=18/54=86/258\). Hence, all three ratios are equal, and the two equations represent the same line; therefore, they are coincident equations. Exam tip: If \(a_1/a_2=b_1/b_2=c_1/c_2\), the pair of linear equations has infinitely many solutions.
