$t = (a - p)/(pr)$

Rewrite the formula so that the term with t is positive on the left hand side.

Isolate the term, then step by step, isolate the variable you want as the subject.

$p + color(red)(prt) = a$

$color(red)(prt) = a - p " ""get rid of +p by -p"$

$prcolor(red)t = a - p" " " get rid of x pr by ÷ pr"$

$t = (a - p)/(pr)$

How do you solve for t in a=p+prt a=p+prt ?
