Re: simultaneous eqn
The 3rd equation tells you that a=b. The second one tells you that b=b, although that's fairly useless.
The 1st one rearranges to give 3a=2c.
Therefore the general solution (a,b,c) will look like (3t,3t,2t), where t is some number.
There are three variables and only two (useful) equations, so we don't know more than that.
Why did the vector cross the road?
It wanted to be normal.
