Right, i don't believe this is a homework question. The only reason I am stating this is because PF are stringent with their rules.
I'm quite confused and I'm not sure how to explicitly state my problem.
The vertices of a triangle are (a,b) (c,d) and (e,f).
This can be arranged into a single matrix.
T = a c e
b d f
with brackets either side i know.
HOWEVER when solving simultaneous equations
2x-3y=5 and -5x+6y=-8
the matrix product
2 -3 X x = 5
-5 6 y 8
is used, so the x values take the first column in this form as oppose to the x values taking the first row in the triangle vertices matrix.
I HAVE TO STATE AGAIN THAT THIS IS NOT A HOMEWORK QUESTION, IT IS JUST A MATTER OF CURIOSITY!
