Question

Solve the matrix.

2 1 8
5 4 6
1 3 1

Answer 1

There is no solution

Answer 2

oops, my bad

2 1 8 1 4 2
5 4 6 * 2 1 1
1 3 1 1 0 1

Answer 3

Forgot the second part. 'sweatdrops anime style.'

Answer 4

the answer should be in the form of
x1
x2
x3
Do you agree?

Answer 5

2 1 8 1 4 2
5 4 6 * 2 1 1 =
1 3 1 1 0 1

(2*1)+ (1*4)+ (8*2) 22
(5*2)+ (4*1)+ (6*1) = 20
(1*1)+ (3*0)+ (1*1) 2

Answer 6

Uh isn't it row*column? That's what I hate about a matrix. So confusing...

Answer 7

heh, not the most conventional method, but my graphing calculator apparently can solve a matrix...

I'll leave this up for a little while just in case people are viewing. I'll delete it later on.

Answer 8

Am I wrong? I'm confused.

Answer 9

Don't worry, I'm confused too. If anyone is well-versed in matrices, please help. I'm going to remove this question in a few hours and just ask my teacher/professor. Good thing it's a passing thing and we aren't going to go into too much detail.

Answer 10

If A is an mXn matric and if B is an nXp matric then the product of AB is the mXp matrix

so the answer should be a 3* 1
