Answer:
[tex]\bold{x= \dfrac{y}{z} }[/tex]
step-wise solution:
[tex]\sf \hookrightarrow \dfrac{y}{x} =z[/tex]
[tex]\sf \hookrightarrow \dfrac{y}{z} =x[/tex]
[tex]\sf \hookrightarrow x = \dfrac{y}{z}[/tex]
Let's see
[tex]\\ \rm\rightarrowtail \dfrac{y}{x}=z[/tex]
[tex]\\ \rm\rightarrowtail y=xz[/tex]
[tex]\\ \rm\rightarrowtail x=\dfrac{y){z}[/tex]
