Question

1/x=y-z/a solve for x

Answer 1

$\frac{1}{x}=y-\frac{z}{a}$

$x=\frac{1}{y-\frac{z}{a} }$,                ( $y-\frac{z}{a}$ = $\frac{y}{1}- \frac{z}{a} = \frac{ya-z}{a}$ )

$x=\frac{1}{y-\frac{z}{a} }$

$x=\frac{1}{\frac{ya-z}{a} }$,               (        $\frac{1}{\frac{ya-z}{a} } =\frac{a*1}{ya-z }$        )

$x=\frac{a}{ya-z }$
