  Well, if you go by the determinant and the co-factor method, it will obviously be very difficult indeed..
  
  But there is another very simple and elegant method for computing inverses very easily..
  You can use row and column operations and try to reduce the given matrix into an identity matrix.
  
  How in the heck do you invert a matrix? And why? | Purplemath. It's very easy..

  you can do much more with this method.. you can also use it to solve algebraic equations..
  
  actually, it's from solving equations, the problem of finding the inverse came about.
  
  suppose we have a system of equations, AX = B, where A is a nxn matrix, X and B are nx1 matrices, to solve this system, we have to solve for X.
  
  This we solve by, X = (A)[sup]-1[/sup]B.
  
  This was basically the need for computing inverse..

  well you can solve it in many ways, depending on what type of matrix you are trying to solve..you may post it here..
