Solve the system of linear equations by using inverse matrix formula. {x−2y=52x−3y=10 Solving System of Equations using Matrix Inverse: If we care given two or more than two equations, then we can write those equations in the form of the matrix given as X=A−1B , w...
Inverse Matrix Formula The first step is to calculate the determinant of the 3 * 3 matrix and then find its cofactors, minors, and adjoint and then include the results in the below-given inverse matrix formula. \[A^{-1} = 1/ |A | Adj (A)\] ...
Whereas for larger order matrices, the adjoint is determined by taking the transpose of the elements of their corresponding cofactors in the matrix. Substitute the values of the determinant of the matrix and the adjoint of the matrix in the inverse formula. Simplifying the values, the inverse of...
