Solve any way you can
2x � y + z = 8
x + 2y + z = -3
x - 2y � z = 7

I am struggling with Matrices not really sure how to solve these and break them down.
Solve any way you can
2x � y + z = 8
x + 2y + z = -3
x - 2y � z = 7
-----------------------------
If you have a calculator with a matrix function
create A
create B
Then X = A^-1*B
----------------------
If you are using Cramer's Method find the determinant
of the 3x3 coefficient Matrix; find the X-Matrix.
Divide the coeff determinant by the x determinant to
solve for x...etc.
----------------------
What kind of "breaking down" are you trying?
Cheers,
