Question

PLEASE HELP ME? I have no idea what to do?

Answer 1

r =
`(txy)/(s)`

Explanation:

multiply both sides by t

txy = rs

flip the equation

rs = txy

divide both sides by s

`(rs)/(s)` =
`(txy)/(s)`

r =
`(txy)/(s)`

Answer 2

multiply t from both sides by t, then divide both sides by s.

it should be txy/s = r
