What will be the value of (a) for (4x+ay=36) and (12x+21y=108) to have infinitely many solutions?

Answer and explanation

Correct answer: 7

For two linear equations to have infinitely many solutions, the ratios of the corresponding coefficients and constants must be equal: 4/12 = a/21 = 36/108. Since 4/12 and 36/108 are both 1/3, we get a/21 = 1/3, so a = 7. Therefore, option C is correct. Exam tip: For infinitely many solutions, all three corresponding ratios must be equal; checking only two ratios is not sufficient.
