[stephnj1]

The following matrix is obtained from a system of equations.

[0 0 6 5 ]
[0 1-4 3 ]
[0 0 2-6 ]

The solution to the system is:

Re: Finite math - matrices: finding system solution

The solution to the system is....

Convert the matrix back into a system of equations, and see what the first and third lines give you.

If you are stuck, please reply showing what you have tried. Thank you.
