this is not a valid matrix multiplication
If you want the dot product of two vectors, then x = -1, y = 4
If you meant to add the two pairs, then x = -2, y = 6
Maybe you should clear things up a bit ...
Solve for x and y:
(x,y)(1,2)=(-1,8)

Question is, find values of x and y.
well, yeah, I got that when you said "Solve for x and y."
But solve what? Exactly what is involved here? Did you even read what I asked, and understand why I'm unclear on just what it is you want?
that notation is not something I've seen before.
points? vectors? Is there supposed to be an operator in there, like
(x,y)+(1,2)=(-1,8)
(x,y)-(1,2)=(-1,8)
(x,y)•(1,2)=(-1,8)
or something else?
