I just started my second year of university and am taking Linear Algebra. I'm a bit rusty on all this systems of equations stuff, so I just want some confirmation, really. If don't have this right, I'd like some guidance
Anyways, the question is worded:
Find all solutions for the following systems of linear equations by writing the solution in parametric form. How many parameters are in the solution?
a.) x + y - z = 2
x - y = 0
Where there are 2 parameters with s and t arbitrary.
As I said, I'm feeling very rusty with this stuff and I don't remember our prof going over in class how to write SYSTEMS in parametric form, only 1 equation in parametric form. My book isn't helping much either.
