Question

3}+4= \frac{5}{6} " alt=" \frac{z}{3}+4= \frac{5}{6} " align="absmiddle" class="latex-formula">

Answer 1

$^{/2}\frac{z}{3} +^{6/}4= \frac{5}{6} \\ \\ \frac{2z}{6} + \frac{24}{6} = \frac{5}{6} => \\ \\ 2z=5-24 \\ 2z=-19 \\ z=-9.5$

Answer 2

$\frac{z}{3}+ \frac{12}{3}= \frac{5}{6}$ ⇒ $\frac{z+12}{3}= \frac{5}{6}$

$z+12= \frac{5\cdot3}{6}=\boxed{2.5}$

$z=2.5-12$

$\boxed{\boxed{\boxed{z=-9.5}}}$
