Answer 1

3z = - 6

z = -6/3

z = - 2

2y - z = 1

2y -(-2) = 1

2y + 2 = 1

2y = 1 - 2

2y = - 1

y = - 1/2

2x - y + 3z = 0

2x - (-1/2) + 3.(-2) = 0

2x + 1/2 - 6 = 0

(2.2x + 1 - 2.6)/2 = 0/2

4x + 1 - 12 = 0

4x - 11 = 0

4x = 11

x = 11/4

R.:

Sistema possível e determinado.

x = 11/4; y = - 1/2; z = - 2
