A subspace W of R is defined by W={(x, 2y, 3z): x, y, z belongs to R }. How to find the dimension of W?
Sorry for the serious mistake in my post . The original question is
Show that W={(x, 2y, 3z): x, y, z belongs to R },where R is the set of real numbers, is a subspace. Find the dimension of W.
I know the solution of the first part. Please help me for the second part.
