What is the value of (c) for the equations (cx+10y=50) and (9x+15y=80) to have no solution?

Answer and explanation

Correct answer: (6)

For two linear equations to have no solution, the ratios of the coefficients of x and y must be equal, but this common ratio must differ from the ratio of the constants: c/9 = 10/15 ≠ 50/80. Since 10/15 = 2/3, c/9 = 2/3 gives c = 6. Also, 50/80 = 5/8, which is different from 2/3, so the lines are parallel and distinct. Hence, the correct answer is (6). Exam tip: First equate the ratios of the x- and y-coefficients, then verify that the constants have a different ratio.
