Question

if x/y is the additive inverse of c/d then what is x/y - c/d?

Answer 1

Given,

x/y is the additive inverse of c/d.

Therefore,
$\frac{x}{y} + \frac{c}{d} = 0$
$\frac{c}{d} = \frac{ - x}{y}$
Therefore,

$\frac{x}{y} - \frac{c}{d}$
$= \frac{x}{y} - (\frac{ - x}{y} )$
$= \frac{x}{y} + \frac{x}{y}$
$= \frac{2x}{y} \: \: soln.$
Hope it helps.
Thanks!
