An augmented matrix for a system of linear equations in x, y, and z is given. Find the solution of the system.

1 1 4 2

0 3 1 7
0 −2 4 0

  (x, y, z) = (-4, 2, 1)

Step-by-step explanation:

See the attachment for the output of a calculator that produces the reduced row-echelon form of the matrix.

The [x, y, z] result vector is the column on the right.

  (x, y, z) = (-4, 2, 1)

_____

Numerous web sites are available for computing the row-reduced form of the matrix, or for solving the system of equations. Your graphing calculator will do it as well.

your answer is the frist one
