Answer
Determinant: -10
Inverse Matrix (from left to right by row):
$-0.3, -0,2$ (row 1)
$-0.1, 0.2$ (row 2)
Work Step by Step
$\frac{1}{(2\times-3)-(2\times2)}$
$\frac{1}{-10}$
Swap the places of A and D, and put negatives in front of B and C.
Multiply each by $\frac{1}{-10}$.
Your answers are: $-0.3, -0,2, -0.1, 0.2$
