Question

What is the answer to this

Answer 1

t =
`(2r)/(r+1)`

Explanation:

Isolate the term with t by adding s to both sides

`(2rs)/(t)` = rs + s = s(r + 1) ← common factor of s

multiply both sides by t to eliminate the fraction

ts(r + 1) = 2rs ( divide both sides by s(r + 1)

t =
`(2rs)/(s(r+1))` ← cancel s on numerator/denominator

t =
`(2r)/(r+1)`
