Solve the system of equations by the Gaussian elimination method.
x − 3y + z = 20
2x − 5y − 3z = 26
x + 4y + z = −15

wait what?

dinamix · Answer

use method of gauss or matrix that's easy way @Mlayton0728

If you have never done this method before, it may not seem easy.

Have you ever done it before?

This is the matrix that you have been given:|dw:1458166273040:dw|Now it is a matter of adjusting the rows so that a solution will evolve.  Persons would do this in different ways.
