Make ax a x the subject of formula x+1x?a

Question 1 Report

Make $\frac{a}{x}$ the subject of formula $\frac{x + 1}{x - a}$

\frac{m - 1}{m + 1}

\frac{m + 1}{1 - m}

\frac{m - 1}{1 + m}

\frac{m + 1}{m - 1}

Answer Details

$\frac{x + a}{x - a}$ = m
x + a = mx - ma
a + ma = mx - x
a(m + 1) = x(m - 1)
$\frac{a}{x}$ = $\frac{m - 1}{m + a}$
