This does what you want (using a randomly generated example):


The solution is in the form of a set of replacement rules for the variables. 
You use the variables /.solution construct to apply these rules to the 
variables, and then use Partition to split the vector of solutions into a 
matrix, which you then display using TableForm (you could use MatrixForm if 
you want brackets drawn round the table).
