Please help on this one?

Answer 1

The answer should be A

Answer 2

On the right side we have st which is the same as s*t or s times t

We want to undo the multiplication that is happening to s, so we have to divide both sides by t

d = s*t

d/t = s*t/t ..... divide both sides by t

d/t = s

s = d/t
