p-----q------------r-----s
1/3 1/2
pr= pq+qr
qs= qr+rs

p-----q------------r-----s
a+b = b+c
a=c

p-----q------------r-----s
1/3 1/2
r=?
Statement 1
pr=qs
Statement 2
pq (1/5)= qr
Statement 1 tells pq=rs but q and r can vary
Statement 2 tells pq=x, qr=5x but r can still vary
together they points are fixed and can solve for r
