1. The problem statement, all variables and given/known data

Write x=(6,-1,-2)T as x=y+z where y belongs to null A and z belongs to row A


2. Relevant equations
The main question asks to find all the fundamental subspaces and their dimensions, which I have already found, and then asks me to find the question i posted above.

the basis for the row space is
{[1,3,1]T, [-1,-5,0]T}

the basis for the nullspace is

3. The attempt at a solution

I don't really know what the question is asking me to do... or how to begin to approach this problem.
If someone could please give me a hint on what they want me to do.

Thanks a lot
