The average of two numbers is the sum of the two numbers, divided by 2. Like this:
x 1 + x 2 2 = a v g
We are given x 1 ,avg and are asked to find x 2 :
63 + x 2 2 = 33
( 63 + x 2 ) = 66
x 2 = 3

Consider a system of linear equations A x = b where A is an n × n matrix. Suppose that b is a non-zero vector such that A t b = 0. Which is true about any such system?
I am given 5 choices for what this means: The system has infinitely many solutions, is inconsistent, is consistent, is over determined, or is in row echelon form.
Unfortunately, I have yet to completely rule out a single one. I don't think it can be over determined, because then wouldn't the equations be undefined based on the fact that if there were more equations than unknowns then A x would not be possible. I don't recall any theorems discussing whether the system is consistent or inconsistent using the transposition and b, which stems to the infinitely many solutions.

I'm reading a textbook at the moment that provides the following linear equation,
α v + v × a = b ,
and asks to solve for v . The form of v is given as
v = α 2 b α ( b × a ) + ( a b ) a α ( α 2 + | a | 2 ) .
It's easy enough to verify that this is the correct solution. However, I can't figure out how I'd solve for v if given just the original equation.
Are there any general approaches to solving this kind of equation systematically?
Edit: a , b and v are all vectors, whereas α is a scalar such that α 0.
