We found a counterexample, so the statement is false.
<h3>Is the statement true?</h3>
Let's use the matrix:
This is a 4x4 matrix with determinant equal to -2.
The inverse matrix is:
If we multiply it by 2, we get:
The adjoint of that is the original matrix, actually:
Which we already know, has a determinant of -2.
So the statement is false, as we found a counterexample.
