$r = p t - 2 s$ $r=pt-2s$

Explanation:

First, we multiply both sides by $t$ $t$ :

From
$p = \frac{r + 2 s}{t}$ $p=(r+2s)/t$ to $p t = r + 2 s$ $pt=r+2s$

Then, we subtract $2 s$ $2s$ from both sides:

$r + 2 s - 2 s = p t - 2 s$ $r+2scolor(blue)-color(blue)2color(blue)s=ptcolor(blue)-color(blue)2color(blue)s$
$r = p t - 2 s$ $r=pt-2s$

$r = p t - 2 s$ $r=pt-2s$

Explanation:

If
$XXX p = \frac{r + 2 s}{t}$ $color(white)("XXX")p=(r+2s)/t$
then

after multiplying both sides by $t$ $t$
$XXX p t = r + 2 s$ $color(white)("XXX")pt=r+2s$

and then subtracting $2 s$ $2s$ from both sides
$XXX p t - 2 s = r$ $color(white)("XXX")pt-2s=r$
...or using the reflexive property for equality: $r = p t - 2 s$ $r=pt-2s$
