Class 10 Mathematics Pair of Linear Equations in Two Variables Conditions for solvabilityExpert

0 reads0 ratings0 helpful

What is the value of (n) for no solution in (2x+ny=7) and (6x+15y=19)?

Answer and explanation

Correct answer: (n=5)

Equating coefficient ratios, (\frac{2}{6}=\frac{n}{15}) gives (n=5). The constant ratio is different, so the pair is inconsistent.
