If (6x+5y=31) and (12x+10y=n) have infinitely many solutions, what is (n)?

Answer and explanation

Correct answer: 62

For two linear equations to have infinitely many solutions, one equation must be a constant multiple of the other. Here, the coefficients of x and y in the second equation are twice those in the first: 12=2×6 and 10=2×5. Therefore, the constant term must also be doubled, so n=2×31=62. Hence, option C is correct. Exam tip: For infinitely many solutions, check a₁/a₂=b₁/b₂=c₁/c₂.
