A)reduced row-echelon form:

b)If there is one solution, give its coordinates in the answer spaces below.

If there are infinitely many solutions, enter z in the answer blank for z, enter a formula for y in terms of z in the answer blank for y and enter a formula for x in terms of z in the answer blank for x.

If there are no solutions, leave the answer blanks for x, y and z empty.

The image displays a system of three linear equations with three variables:

1. $ x + 2y - z = -3 $

2. $ 3x + 9y - 9z = -21 $

3. $ 3x + 8y - 7z = -17 $

This system of equations can be used in linear algebra to find the values of the variables $ x $, $ y $, and $ z $ that satisfy all three equations simultaneously. Methods such as substitution, elimination, or matrix operations can be applied to solve this system.
