solving linear systems of equations using matrices

[Twins]

I don't know how to do matrixs. A solve them using row reduction.

1. 2w-3y+4z=54
6x+4y-3x= -29
-5w+3x+y-z= -38
4w-6x+2y-5z=-31


2. 3a+2b+6c+4d+5e= -3.7
-8a-4b+2c-6d+2e= -35.2
6a+5b+12c+7d+3e=19.8
-8b-3c+5d-46=61.7
2a+7b+4c+2d-2e=3


3. 6r+4s-3t-2v+4w+2z=74.52
4r-3s+7t+6v+3w-6x= -115.83
-3r+2s+6t-3v-10w+0.5x=4.22
2r-6s+9t-9v+10w-3x= -11.74
8r+7s+4t+2v-6w+7x=49.87
12r-3s-2t-v+7w+3x=27.85

Can you please help me? I need this by tomorrow. Thank you!

Unfortunately, we cannot teach courses here. If somehow you missed the chapter on matrices and matrix operations, I'm afraid we cannot replicate that instruction here.

Please try a search engine for lessons on matrices, matrix row operations, and solving systems using matrices. If you study hard (and maybe meet with a tutor, face-to-face, for a few hours a week, or daily), you should be able to learn the material in a week or two.

Good luck!

Eliz.
