The coefficient matrix of a linear system has four rows and four columns.

Question

The coefficient matrix of a linear system has four rows and four columns.
   1) How may equations are there in this linear system?
   2) How may variables are there in this linear system?
   3) If this coefficient matrix has a pivot in each column, how many 
       solutions does the system have? (Does it have no solutions, one 
       solution, or  many solutions?) Why?

Please help me ;)

google "coefficient matrix has a pivot in each column" for several discussions.
