WebFirst, we need to find the inverse of the A matrix (assuming it exists!) Using the Matrix Calculator we get this: (I left the 1/determinant outside the matrix to make the numbers simpler) Then multiply A-1 by B (we can use the Matrix Calculator again): And we are done! The solution is: x = 5 y = 3 z = −2 WebNote: also check out Matrix Inverse by Row Operations and the Matrix Calculator . We can calculate the Inverse of a Matrix by: Step 1: calculating the Matrix of Minors, Step 2: then turn that into the Matrix of Cofactors, Step 3: then the Adjugate, and; Step 4: multiply that by 1/Determinant. But it is best explained by working through an example!
