The inverse of a matrix A is A⁻¹, just as the inverse of 2 is ½. We can solve equations by multiplying through by inverses; it's similar with matrices.
Find the inverse of the matrix A=[1−13212−2−21] Step 1: Find det(A). According to our determinant formula for a 3×3 matrix: det(A)=1⋅|12−21|+1⋅|22−21|+3⋅|21−2−2|=1(1+4)+1(2+4)+3(−4+2)=1(5)+1(6)+3(−2)=5+6−6=5. Since ...
