Is it solvable?

How convenient!

So when he is solving equations he can always use the phrase "and then magic happens..."

My favorite was always "...which involves mathematical concepts that even I don't understand"

More accurately, the solution set is a line in 3-space. (A "graph" could be a line, a plane, a set of discrete points, a hyperbolic paraboloid, the interior of a cube, and so on.)

The coefficient matrix for the system is:

[1 0 13/2]
[0 1 -3/2]

and augmented matrix for this system is:

[1 0 13/2 29/2]
[0 1 -3/2 -9/2].

The dimension of the row space for the coefficient matrix is 2, as is the dimension of the row space for the augmented matrix; thus, the system is soluble. The dimension of the solution space is 3 - 2 = 1.

The solution space is the set of all points in 3-space having the form ((29 - 13t) / 2, (3t - 9) / 2, t), -∞ < t < ∞.

I'm pretty sure this is what Magician looks like...

I heard you can get that power from a bolt of lightning

More blond, less gray.

Now I'm outta' here: my algebraic topology book just arrived from Amazon!

Hey me too.. nothing I like more than sitting by the fire, reading algebraic topology.
