hartnn · Answer

you'll be able to find Y in terms of W and Z 
to get 3X in 2nd equation, you multiply  W+Z=X+Y by 3 
so that you can replace '3X' by '2W' (from first equation.)
what u get ?

anonymous · Answer

Sure, but where does the z go?

anonymous · Answer

only in terms of W!!!

hartnn · Answer

thats what i am saying, you won't be able to find it ONLY in terms of W , it seems impossible to me..... unless more equations are given.....

hartnn · Answer

do u understand how you will not be able to eliminate Z ??

hartnn · Answer

i wonder what hba is typing from last 8 minutes...

hba · Answer

@hartnn If we make more equations it is quite possible to eliminate.

hba · Answer

I am solving it

hartnn · Answer

ohh.. go ahead, surprise me ...

hartnn · Answer

with 2 equations, you''l only be able to eliminate 1 variable....

hba · Answer

Well i ended up getting their values lol and yeah @hartnn Your'e Right :)
