Question 447312: ind the ordered triple of these equations.
x - 2y + 3z = -3
2x - 3y - z = 7
3x + y - 2z = 6
Answer by Cabdiqafaar(9) (Show Source): You can put this solution on YOUR website!
x-2y+3z=-3
2x-3y-z=7
3x+y-2z=6
D=|1 -2 3
2 -3 -1
3 1 -2|= 38
Dx=|-3 -2 3
7 -3 -1
6 1 -2| = 38
Dy= | 1-2 -3
2 7 -1
3 6 -2| = -38
Dz= | 1 -2 -3
2 -3 7
3 1 6| = -76
x=Dx/D = 38/38 = 1
y= Dy/D = -38/38 = -1
z= Dz/D = -76/38 = -2
