Just attempting to solve a few matrices but do not seem to be getting the answer right! Probably easy but im struggling. Also, I'm sorry, I couldnt figure out how to code a matrix into the format so it looks weird.
For this problem, I am attempting to find MX when:
MX= (Inverse of X x X) x M
1 2 3
1 1 -1
2 4 7
First, find X^-1 (Inverse of X)
Next, find M if MX=
-13 -5 17 -13 38
11 -6 6 -24 -5
-32 -7 35 -21 86
Once again, sorry about the formatting of the matrices. hopefully someone can help me out because I think I'm stuffing up the inverse step.
