You can put this solution on YOUR website! How can you create a system of equations with the solutions:
u=1
v=-4
w=2
x=0
y=-5
z=8
-----------
The simplest set is:
u=1
v=-4
w=2
x=0
y=-5
z=8
---------
You can make up any coefficients:
Au + Bv + Cw + Dx + Ey + Fz = ??
Put in numbers for A to F, multiply by the values of u thru z and calculate what's on the right side.
