Question
How would I write a matrix equation for...
0.2x+0.04y-0.2z=-.03
1.1x-0.6y+0.7z=0.5
0.25x+0.3y-0.35z=0.1
Would you be able to explain WHY you are doing your particular steps (my book offers explanations for similar problems, but I do not understand why each step takes place)
Thanks for your help

Answers
you would have a 3x3 matrix
.2 .04 .2
1.1 .5 .7
.25 .3 35
multiplied by the column matrix
x
y
z
and equal that to the column matrix
.03
.5
.1
I assume you know how to multiply one matrix by another.
