hey ive been given a system of equations:
i put this into an augmented matrix and got w+x+y=4 so im guessing that this gives a solution set which is that plane..how do i write this mathematically and am i correct??
(many linear algebra tests would write the solution in the latter form, separating pieces corresponding to the independent parameters. But you don't HAVE to; there is absolutely nothing wrong with writing it the other way).
