a1x + b1y + c1z = d1

a2x + b2y + c2z = d2

a3x + b3y + c3z = d3

For example:

x1+x2-2x3=-3

2x1+x2-x3=1

x1-x2+3x3=8

Untie: 
D = 
	1  1 -2
	2  1 -1
	1 -1  3
	= 1

D1 = 
	-3  1 -2
	1  1 -1
	8 -1  3
	= 1

D2 = 
	1 -3 -2
	2  1 -1
	1  8  3
	= 2

D3 = 
	1  1 -3
	2  1  1
	1 -1  8
	= 3

So x1 = D1/D = 1
     x2 = D2/D = 2
     x3 = D3/D = 3
