OpenStudy (unklerhaukus):

ah, lesson 6 .

OpenStudy (anonymous):

yes

OpenStudy (anonymous):

this is a hard one i dont know what to do

OpenStudy (unklerhaukus):

you have product of matrices ? y/n

OpenStudy (anonymous):

no just A/X

OpenStudy (anonymous):

?????????????

OpenStudy (unklerhaukus):

A divided by X ?

OpenStudy (anonymous):

is A 1 and X=27 ???

OpenStudy (anonymous):

the letter X

OpenStudy (unklerhaukus):

im getting the picture now

OpenStudy (anonymous):

so is it 27

OpenStudy (anonymous):

?

OpenStudy (unklerhaukus):

try that substitution once again

OpenStudy (anonymous):

?

OpenStudy (unklerhaukus):

\[A/X=?\] if\[ A=1,\qquad X=27\] \[A/X=?=1/27\]

OpenStudy (anonymous):

so i shod go with 1/27

OpenStudy (unklerhaukus):

does that seam logical ?

OpenStudy (anonymous):

yes but i dont knnow if A=1 or X=27

OpenStudy (unklerhaukus):

ah dear then substituting them in probably wont help, \[A/X=?\]

OpenStudy (anonymous):

all it sed was A*X=?

OpenStudy (unklerhaukus):

\[A*X=?\]\[A\cdot X=?\]\[A\times X=?\]

OpenStudy (anonymous):

YES

OpenStudy (unklerhaukus):

what is ?

OpenStudy (anonymous):

A times X =

OpenStudy (unklerhaukus):

\[A\times X=?\]\[A\times X=\]\[A\times X=0\] one of these?

OpenStudy (anonymous):

2

OpenStudy (unklerhaukus):

if \(A,X\in \mathbb R\) \[A\times X=X\times A\]
