Hi,
I have a system of equations with 3 unknowns, the coefficients are shown as a matrix below, and wondered if this would be a good way to solve for the variables?
2270 -1800 0 | 15
-1800 3480 -680 | 0
0 -680 1150 | -8
I'd like to calculate all the steps manually, but all the matrix examples i've seen so far seem to use much simpler, single digit numbers, so what i'm trying to ask in a roundabout way is; do numbers this size lend themselves to a matrix, or is their a better way to solve?
Thanks for looking, and any help is much appreciated.
