The goal in solving an equation is to get the variable by itself on one side of the equation and a number on the other side of the equation. To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation.
An inverse matrix is the matrix that is multiplied by the original square matrix to derive the identity matrix, which contains values of 1 on the diagonal and 0 elsewhere. This property makes it useful for solving systems of equations that include many variables.ype without quotes: =MINVERSE(A1:C3). Replace the cell reference A1 with that of the upper left corner of your matrix, and C3 with the cell reference of the lower right corner of your matrix. Hold down both the Ctrl and Shift keys; press Enter..
