**Matrix Multiplication Calculator (1 x 4) and (4 x 4)**

Think of Cramer's rule… With matrix mode you can calculate the 3 x 3 minor directly…... Question 18759: I have to solve this 4x4 matrix using Cramer's Rule: 4x + 0y + 3z - 2w = 2 3x + 1y + 2z - 1w = 4 1x - 6y - 2z + 2w = 0 2x + 2y + 0z - 1w = 1 Once I get to finding the determinants of the three 3x3 matrices, I am completly lost. Do you solve like a normal 3x3 and just multiply the determinent found by the number on the outside? After that is it simply repeating the same process

Question 18759: I have to solve this 4x4 matrix using Cramer's Rule: 4x + 0y + 3z - 2w = 2 3x + 1y + 2z - 1w = 4 1x - 6y - 2z + 2w = 0 2x + 2y + 0z - 1w = 1 Once I get to finding the determinants of the three 3x3 matrices, I am completly lost. Do you solve like a normal 3x3 and just multiply the determinent found by the number on the outside? After that is it simply repeating the same process... The determinant can be used to solve a system of equations. The determinant can tell you if the matrix is invertible or not (it is not if the matrix is 0). The determinant can tell you if the matrix is invertible or not (it is not if the matrix is 0).

Question 18759: I have to solve this 4x4 matrix using Cramer's Rule: 4x + 0y + 3z - 2w = 2 3x + 1y + 2z - 1w = 4 1x - 6y - 2z + 2w = 0 2x + 2y + 0z - 1w = 1 Once I get to finding the determinants of the three 3x3 matrices, I am completly lost. Do you solve like a normal 3x3 and just multiply the determinent found by the number on the outside? After that is it simply repeating the same process how to use multiple 3d obejcts element It is best to use computers to solve a large system of equations. However, you can solve for the determinant of a 4-by-4 matrix by replacing the values in the rows and using the "upper triangular" form of matrices. This states that the determinant of the matrix is the product of the numbers in the diagonal when everything below the diagonal is a 0.
