Explicación:

x - y + z = 2

x−y+z+y=2+y

x+z=y+2

x+z+−z=y+2+−z

x=y−z+2

x + y + z = 4

x+y+z+−y=4+−y

x+z=−y+4

x+z+−z=−y+4+−z

x=−y−z+4

2x + 2y - z = -4

2x+2y−z+−2y=−4+−2y

2x−z=−2y−4

2x−z+z=−2y−4+z

2x=−2y+z−4

2x /2 = −2y+z−4 /2

x=−y+ 1 /2  z−2

2x + y - 3z = -1

2x+y−3z+−y=−1+−y

2x−3z=−y−1

2x−3z+3z=−y−1+3z

2x=−y+3z−1

2x /2 = −y+3z−1 /2

x= −1 /2 y+ 3 /2 z+ −1 /2

x - 3y - 2z = -12

x−3y−2z+3y=−12+3y

x−2z=3y−12

x−2z+2z=3y−12+2z

x=3y+2z−12

3x - 2y - z = -5

3x−2y−z+2y=−5+2y

3x−z=2y−5

3x−z+z=2y−5+z

3x=2y+z−5

3x /3 = 2y+z−5 73

x= 2 /3 y+ 1 /3 z+ −5 /3

2x + 3y - z = 1

2x+3y−z+−3y=1+−3y

2x−z=−3y+1

2x−z+z=−3y+1+z

2x=−3y+z+1

2x /2 = −3y+z+1 /2

x= −3 /2 y+ 1 /2 z+ 1 /2

6x - 2y - z = -14

6x−2y−z+2y=−14+2y

6x−z=2y−14

6x−z+z=2y−14+z

6x=2y+z−14

6x /6 = 2y+z−14 /6

x= 1 /3 y+ 1 /6 z+ −7/3

3x + y - z =1

3x+y−z+−y=1+−y

3x−z=−y+1

3x−z+z=−y+1+z

3x=−y+z+1

3x /3 = −y+z+1 /3

x= −1 /3 y+ 1 /3 z+ 1 /3

Listo preciosa , recuerda tener en cuenta la ley de signos:

+ x + = +

+ x - = -

- x + = -

- x - = +
