Question

Inverse matrix method

Answer 1

Step-by-step explanation:

A is called the matrix of coefficients. This result gives us a method for solving simultaneous equations. All we need do is write them in matrixform, calculate the inverse of thematrix of coefficients, and finally perform a matrix multiplication. We need to calculate the inverse of A = ( 1 2 3 −5 \.
