If f (x) f ( x) is a given function, then the … WebB B. is the matrix representing the constants. Using matrix multiplication, we may define a system of equations with the same number of equations as variables as: \displaystyle A\cdot X=B A⋅X = B. To solve a system of linear equations using an inverse matrix, let. A A. be the coefficient matrix, let. X X. be the variable matrix, and let.

The inverse of A is A-1 only when AA-1 = A-1A = I. To find the inverse of a 2x2 matrix: swap the positions of a and d, put negatives in front of b and c, and divide everything by the determinant (ad-bc). Sometimes there is no inverse at all.
WebStep 1. Find the determinant. To determine the inverse of a matrix, you first need to multiply diagonally. Multiply the number in the top left by the number in the bottom right. We highlighted those values in pink. (3x3=9) Multiply the number in the top right by the number in the bottom left.
