Data Sufficiency (DS) | Re: P, Q, R , S, T, U are positive integers, such that S/P + T/Q = U/R, is

Before we do anything we need to rewrite the statement and isolate- that way we can simplify and find the true fundamental question

s/p= (qu-tr)/(qr) - to rewrite in terms of p just flip the right handside and multiply the top by "s"
p= qr*s/(qu-tr)

Statement 1
Too many possibilities

insuff

Statement 2
Several possiblities

Statement 1 and 2
