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

0 reads0 ratings0 helpful

For no solution in (5x-2y=c) and (15x-6y=21), what condition should (c) satisfy?

Answer and explanation

Correct answer: (c\neq7)

The coefficient ratio is (\frac{1}{3}). For no solution, (\frac{c}{21}\neq\frac{1}{3}), hence (c\neq7).
