Linear systems

Hello.

I have a question about linear systems.

Ex: we have 2 equations with 3 unknown.

2x1+1x2+x3 = 5
1x1+ax2+x3 = 2


What to do with a if we put it in a matrix? Do we set it to 1 since x2 is behind or 1a?

Like
[ 2 1 1 | 5]
[ 1 1 1 | 2]

Or how Would you do?
I am just curious

Hello, Predator!

What are the instructions?

I will assume that we are to solve the system.
And maybe answer the question:
[color=beige]. . [/color]"For what value(s) of will the system have no solutions?"
