Respuesta :
First, expand the product on both members of the equation:
[tex]\begin{gathered} -6(k+3)=-3(2k+7) \\ \Rightarrow-6k-6\cdot3=-3\cdot2k-3\cdot7 \\ \Rightarrow-6k-18=-6k-21 \end{gathered}[/tex]Notice that the term -6k appears at both sides of the equation. Then, we can cancel them:
[tex]\Rightarrow-18=-21\text{ !}[/tex]This is a contradiction. Then, the equation does not have a solution.
