Question

T=1/p+1/q
make q the subject​

Answer 1

q =
`(p)/(tp-1)`

Explanation:

Given

t =
`(1)/(p)` +
`(1)/(q)`

Multiply through by pq to clear the fractions

tpq = q + p ( subtract q from both sides )

tpq - q = p ← factor out q from each term on the left side

q(tp - 1) = p ← divide both sides by (tp - 1)

q =
`(p)/(tp-1)`
