ok, i have my midterm tomorrow and am doing the online assignment, i finished everything easily but this question i just dont get:banghead: :banghead: so if u guys can help that would be awesome!




Question 1 [10 points]
Find a matrix X such that AX=B, where

A =
12 1 -6 0 -8
2 0 0 1 10
3 0 0 -1 -11

B=
-81
22
-28



A is not invertible since its not a square... so i cant do that
that means A(A)^-1 * X = (A)^-1B is out of the questoin

what am i suppose to do???
