Xfaaa me urgee, gracias! :) ​

Answer 1

Respuesta:

Explicación paso a paso:

$\frac{1}{4}k=3(-\frac{1}{4}k+3)\\\\\frac{1}{4}\frac{1}{3}k=-\frac{1}{4}k+3 \\\\\frac{1}{4}\frac{1}{3}k+\frac{1}{4}k=3\\\\k(\frac{1}{4}\frac{1}{3}+\frac{1}{4})=3\\\\k = \frac{3}{\frac{1}{4}\frac{1}{3}+\frac{1}{4} }$

puede quedar así o la resuelves

$k = \frac{3}{\frac{1}{4}\frac{1}{3}+\frac{1}{4} }\\\\k =\frac{3}{\frac{1}{12}+\frac{1}{4} }\\\\k =\frac{3}{\frac{1+3}{12} } \\\\k = \frac{3}{\frac{4}{12} } \\\\k=\frac{3}{\frac{1}{3} }\\\\k=9$
