Answer 10

x + 3y - z = 2
x - 2y + 3z = 7
x + 2y - 5z = -21

[1......3.....-1....2 ] R1 - R2 ---> R2
[1.....-2......3....7 ] R1 - R3 ---> R3
[1......2.....-5..-21 ]
----------------------

[1......3.....-1....2 ] R2 - 5R3 ---> R3
[0......5.....-4...-5 ]
[0......1......4...23 ]
----------------------

[1......3.....-1....2 ] 5R1 - 3R2 ---> R1
[0......5.....-4...-5 ] R3/-24----> R3
[0......0....-24..-120 ]
----------------------

[5......0......7...25 ] R1 - 7R3 ---> R1
[0......5.....-4...-5 ] R2 + 4R3 ----> R2
[0......0......1....5 ]
----------------------

[5......0......0...-10 ] R1/5 ----> R1
[0......5......0...15 ] R2/5 ----> R2
[0......0......1....5 ]
----------------------

[1......0......0...-2 ]
[0......1......0...3 ]
[0......0......1....5 ]
----------------------

therefore; x = -2 , y = 3 , z = 5 <===== B
