Question

Let A [ a1, a2, a3] be a 3x3 non-singular matrix, where
1 a ,[a1, a2, a3] are the three columns of A. Define a 3 x 4
matrix B by
B[ 2a1+4a2-2a3 , -a1 -4a2 +3a3 ,a2-a3 , 3a1-2a2+6a3]
Show that the system of linear equations Bx= b is consistent for every
3 x 1 matrix b.'
how can i solve it

Answer 1

IDK how to solve it, sry.
