If (5x+2y=16) and (10x+4y=n) have infinitely many solutions, what is (n)?

Answer and explanation

Correct answer: 32

For infinitely many solutions, both linear equations must represent the same line. The coefficients on the left side of the second equation are twice those in the first equation: 10 = 2×5 and 4 = 2×2. Therefore, the constant on the right side must also be doubled, so n = 2×16 = 32. Hence, option D is correct. Exam tip: For infinitely many solutions, the ratios of the corresponding coefficients and constants must be equal.
