$r=nt-ns$

The algebraic equation we have is:

$r/n+s=t$

We can solve this by:

1) Subtract $s$ from each side

$->color(blue)r/n+scolor(red)(-s)=tcolor(red)(-s)$

$->color(blue)r/n=t-s$

2) Multiply each side by $n$

$->color(blue)r/n color(red)(*n) = (t-s)color(red)(*n)$

$->color(blue)r=(t-s)n$

$color(blue)r=nt-ns$

Thus, we have the answer:

$r=nt-ns$
