1/3(-2p+6q-9r)-1/6(-4p-18q+24r)
equalising the denominator by 6 we get
=1×2/3×2(-2p+6p-9r)-1/6(-4p-18q+24r)
=2/6(-2p+6p-9r)-1/6(-4p-18q+24r)
= -4p+12q-18r/6+4p+18q-24r/6
= -4p+4p+12q+18q-18r-24r/6
= 12q+18q-18r-24r/6
=30q-42r/6
=6(5q-7r)/6
5q-7r=0
5q=0+7r
5q=7r
q=7r/5
and
5q-7r=0
-7r=0-5q
-7r= -5q
7r=5q
r=5q/7
Therefore q=7r/5 and r=5q/7
Hope you got it :)))
