\(\frac{z}{3}+4= \frac{5}{6}\)
\(\frac{z}{3}+ \frac{12}{3}= \frac{5}{6}\) ⇒ \(\frac{z+12}{3}= \frac{5}{6}\)\(z+12= \frac{5\cdot3}{6}=\boxed{2.5}\)\(z=2.5-12\)\(\boxed{\boxed{\boxed{z=-9.5}}}\)
\(^{/2}\frac{z}{3} +^{6/}4= \frac{5}{6} \\ \\ \frac{2z}{6} + \frac{24}{6} = \frac{5}{6} => \\ \\ 2z=5-24 \\ 2z=-19 \\ z=-9.5\)
