How would I write a matrix equation for...
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
you would have a 3x3 matrix
.2 .04 .2
1.1 .5 .7
.25 .3 35
multiplied by the column matrix
and equal that to the column matrix
I assume you know how to multiply one matrix by another.
