[tex]Despejar\ z \\ \\ \frac{5}{6}b- \frac{2}{3}z = \frac{1}{9} \\ \\ - \frac{2}{3}z = \frac{1}{9} - \frac{5}{6}b \\ \\ z= ( \frac{1}{9}- \frac{5}{6}b) : -\frac{2}{3} \\ \\ z= \frac{1}{9}:- \frac{2}{3} - \frac{5}{6}b : -\frac{2}{3} \\ \\ z= - \frac{1}{6}+ \frac{5}{4}b [/tex]
Espero que te sirva, salu2!!!!
