Find the solution set of triplets that fulfil this system using Gauss-Jordan:
First of all, I don't see any variable there. I suppose it doesn't matter and I proceed normally:
So, this is the staggered reduced form.
This is an homogeneous system (because of the null column), thus one solution is .
Other than that, I have to check out the range of the system. The range is , which is less than the number of columns... what is the number of columns?
