FInd the inverse of this function why is this incorrect

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

Can you show your process?

when I take the inverse using the formula 1/(ad-bc) this becomes 1

so i keep it as is but flip the sign on the b and c matrix

but the answer i get is wrong

[hollow condor]

The determinant isn't 1.

[cedar hare]

what is it

[hollow condor]

Well, try calculating it again.

[cedar hare]

1/(4e^3t)(e^4t)

no?

[hollow condor]

Well, don't invert it yet. We are finding just the determinant.
