Answer» Correct option is (B) Any real number except 3 For both lines has exactly one solution (unique solution), we have \(\frac{a_1}{a_2}\neq\frac{b_1}{b_2}\) \(\Rightarrow\) \(\frac{2P}2\neq\frac31\) \(\Rightarrow\) \(P\neq3\) Hence, for any real value of P except 3, the given pair of linear equations has exactly one solution. Correct option is B) Any real number except 3 |
