Question

sistema.
x + y + z = 0
x - y+z=0
x -y-z=0​

Answer 1

Respuesta:

a) Alternate form:

z = -x - y

Real solution:

z = -x - y

Solution:

z = -x - y

b) Alternate forms:

x + z = y

z = y - x

Real solution:

z = y - x

Solution:

z = y - x

c) Alternate forms:

x = y + z

z = x - y

Real solution:

z = x - y

Solution:

z = x - y
