Im trying to solve for x1 x2 x3 and x4 for this matrix but I keep getting errors. Matrix A contains all the coefficients for x1 x2 x3 x4 respectively and Matrix B contains what it is equal to. I wrote the following code which in theory should work but it keeps saying I provided 5 arguments or something like that.

First, find the inverse of the coefficient matrix. The inverse of [ 7 5 3 − 2] is. 1 7 ( − 2) − ( 3) ( 5) [ − 2 − 5 − 3 7] = − 1 29 [ − 2 − 5 − 3 7] = [ 2 29 5 29 3 29 − 7 29] Next, multiply each side of the matrix equation by the inverse matrix . Since matrix multiplication is not commutative, the inverse matrix should be at the left on each side of the matrix equation.

To solve the equations, we need to find matrix X. It can be found by multiplying the inverse of matrix A with B, which is given as \( X = (A^{-1})B\). To find the inverse of A, we will need the determinant and adjoint of matrix A. To find the determinant of matrix A, we will follow the below steps: \( |A| = \begin{vmatrix} 1 & 1\\ 2 & 3\\ \end{vmatrix}\)

To solve the system of equations with matrices, we will follow the steps given below. Arrange the elements of equations in matrices and find the coefficient matrix, variable matrix, and constant matrix. Write the equations in AX = B form. Take the inverse of A by finding the adjoint and determinant of A.

With matrices the order of multiplication usually changes the answer. Do not assume that AB = BA, it is almost never true. So how do we solve this one? Using the same method, but put A-1 in front: A-1 AX = A-1 B. And we know that A-1 A= I, so: IX = A-1 B. We can remove I: X = A-1 B. And we have our answer (assuming we can calculate A-1)
