The tests cases used an exact test for equality. In terms of floating point numbers, this is incorrect as a test, because it can fail to recognize entirely valid solutions, and there are many ways to validly solve this problem. As such, I modified the test cases to use a tolerance on the result.

inv(A)*b solution not working for test case 1.. Am I wrong with this?

It's the floating-point precision that matters.
