Coefficient Matrices question.

1. 5x +7y = -11
3x + 4y = -6

2. -3x + y = -7
-8x + 5y =-14

3. x+ 2y + 2z =18
2x + 3y + 3z = 29
x - y - 2z =-6

4. 2x + 2y + 3z =9
3x + 3y + 4z = 13
x +2y + 4z =9

vocaloid · Answer

are you asking what the coefficient matrices would be?

clamin · Answer

yes

vocaloid · Answer

just take the coefficients and put them into a matrix

vocaloid · Answer

example:

5x +7y = -11
    3x + 4y = -6

what are the coefficients?

clamin · Answer

i know how to do it but i dont know how to solve it to get the x, y, z

vocaloid · Answer

find the inverse of the coefficient matrix
