If |A| doesnt = 0 what is the solution to AX = B?

[me....]

I have NO idea how to do this. The EXACT problem is...

"If |A| doesnt = 0 what is the solution to AX = B?"

That right there is all it gives and i have no idea how to do it...

If the determinant of a matrix is zero, does it have an inverse? :?:

If the matrix is invertible, what is one way to solve a system of equations? :wink:

i dont know...i still dont get it....the determinant isnt 0....cuz it says it wasnt...

Do you know anything about the use of matrices to solve systems of equations?

Yes, I know. However, I didn't ask you to determine whether the determinant was zero. I asked what a zero determinant would tell you about the inverse of the matrix. :?

From your reply, it would appear that you need to study inverse matrices and solving matrix equations. Unfortunately, we cannot provide the week or so of classes that you need. Sorry!

Please consider either studying from lessons online (since your book and classroom lectures were not apparently sufficient), or else please think about hiring a local qualified tutor. If you set aside a few hours a week (daily would be best), you may be able to get caught up with the class in very little time. :idea:

My best wishes to you in your studies.
