Question 370426
I must solve this system if possible, I worked the system and received the answer below...Im wondering if it is correct.

3x+y+z=0
2x-y+z=0
2x+y+z=0

My answer is 

z=4, y=-25, x=18
-----------------
Sub your answers into the eqns:
3x+y+z=0
3*18 - 25 + 4 = 33, not 0
--> not correct.
Hint:  when all the coefficients are zero,
x = y = z = 0
