You are asking for what does there exists real numbers so that ?

This leads to the equations,

We want this system to be__consistent__i.e. it has solutions.

Convert this equation into a matrix,

Now use Gauss-Jordan elimination to reduce it you should get on the bottom row something like: .

Then in order for it to be consider that expression of needs to be equal to zero.
