Question 324812: Find x1 and x2 for(show steps involved):
[-4 5][x1]+[ 3]=[71]
[-2-4][x2] [18] [ 0]
*note* both lines are part of the same matrix equation, I didn't know how to type it as a continuous multi-line matrix bracket. Answer by Fombitz(32388) (Show Source):
You can put this solution on YOUR website! I think this is what you mean.
Simplify,
.
.
.
[A][x]=[b]
[A]inv[A][x]=[A]inv[b]
[x]=[A]inv[b]

Find the inverse of the coefficient matrix [A],
det([A])=
[A]inv=
[x]=
