yes, it is true that the transpose of the transpose of a matrix is the original matrix
i believe you are refering to the matrix on a pdc drill bit. if all the cutters were missing when you pooh, chances are you have ground into the bits body, or the "matrix".
I could do that if you gave me the original matrix.
When its matrix is non-singular.
by elimination,substitution or through the matrix method.

To find the original matrix of an inverted matrix, simply invert it again. Consider A^-1^-1 = A^1 = A
That is called an inverse matrix

A mathematical equation.
Nothing, but a two dimensional array can be used to represent a matrix.

When its matrix is non-singular.
Create a matrix of the coefficients of each equation. The solutions to the equations should make up the rightmost column of the matrix. Then, row reduce the matrix until you are able to rewrite the equations and solve them. The matrix should be a 4x5 matrix (4 rows and 5 columns) for four equations with four variables. This is known as a system of equations.

Next to your 4x4 matrix, place the 4x4 identity matrix on the right and adjoined to the one you want to invert. Now you can use row operations and change your original matrix on the left to a 4x4 identity matrix. Each time you do a row operation, make sure you do the same thing to the rows of the original identity matrix. You end up with the identity now on the left and the inverse on the right. You can also calculate the inverse using the adjoint. The adjoint matrix is computed by taking the transpose of a matrix where each element is cofactor of the corresponding element in the original matrix. You find the cofactor t of the matrix created by taking the original matrix and removing the row and column for the element you are calculating the cofactor of. The signs of the cofactors alternate, just as when computing the determinant
