The pair of eqn does not have any solution if

{tex}\begin{array}{l}\frac{a1}{a2}=\frac{b1}{b2}\neq\frac{c1}{c2}\\\mathrm{Putting}\;\mathrm{all}\;\mathrm{values}\;\mathrm{we}\;\mathrm{get}\\\frac23=\frac{-\mathrm k}2\neq\frac{-3}{-1}\\\;\mathrm{or}\;-3\mathrm k=4\\\mathrm k=-\frac43\\\\\end{array}{/tex}
