What conclusion follows from comparing the ratios of (a) and (b) in (7x+4y=18) and (3x+2y=10)?

Answer and explanation

Correct answer: (7/3 \ne 4/2), so one unique solution

Here (7/3 \ne 4/2), so the lines will intersect at one point. If the first two ratios differ, one unique solution is obtained.
