1. ## inverse matrices

how do you find the inverse of an inconsistent 3x3 matrix??
thanks

2. Use jordan-gaussian method for finding the inverse.

You don't. If a matrix is inconsistent (the equation Ax= b has no solution) then it has no inverse. If A has an inverse,then $A^{-1}Ax= x= A^{-1}b$ contradicting the definition of "inconsistent".
