## Given-Find: Undefined Variable

Hello, I am working on some Laplace Transform problems and the problem got messy quickly and I figured I would just use a given find to solve for A, B, C, and D(for the partial fraction). But I am unfortunately running into an issue that I have seen before but I cannot remember how I resolved it. The reoccuring issue is the last variable in the matrix will appear to be undefined when it is clearly defined beforehand. I want to make sure to write down how to properly use the given find so this issue will not occur again. Any help would be greatly appreciated.

I am illiterate when its comes to zipping files, but I think I may have done it correctly.

You can use the "Minerr" function instead of "Find" (which tries to find an exact solution).

Okay but how is A=1.47, when underneath given I clearly defined
12A=30 with the Boolean equal sign

Thank you very much, like I said this was an annoying partial fraction problem I must have made a math error at some point or the solutions manual is incorrect. Which that isn't the first occasion, anyways thank you for help.
