Calculus - Linear Algebra

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 ;)

  1. #1. Really? You just said it had 4 rows, so ...

    #3. Looks like you better read up on what such a set of pivots means
    google "coefficient matrix has a pivot in each column" for several discussions.
