OK

X + Y + Z =  10

Substitute X and put 0 for Y & Z
Substitute Y and put 0 for X & Z
Subtitue Z and put 0 for X & Y

i am not the one to talk, but it seems that you are saying 0+0+0=10... which is like dividing by zero...

No...

One variable at one time.

X = 10, Y= 0, Z = 0
X = 0, Y = 10, Z =0
X = 0, Y = 0, Z = 10

X = 0, Y = 0, Z = 10
