WebWhy does the augmented matrix method for finding an inverse give different results for different orders of elementary row operations? 1 Using elementary row operations to solve intersection of two planes WebStep 1: The first step while finding the inverse matrix is to check whether the given matrix is invertible. For this, we need to calculate the determinant of the given matrix. If the determinant is not equal to 0, then it is an invertible matrix otherwise not. If it is invertible, proceed to the next step.
