just like to check if ive got these right. if not can you help??
make the subject (q) p(q+r)=2(qp)ans q=pr+2p/(2p)
make the subject (p) p+3=qp+r/(2) ans p=r6/(2q)
make the subject (r) p(rq)=2+3(qr) ans r=2+3q+pq/(p+3)
make the subject (x) y=rqp/(x) ans
x=rqp/(y)

i think i've already answered that one,, you reposted it right?
so there,, =)
