Determine whether there is a unique solution, no solution, or an infinite set of solutions with one or two parameters.

I'm supposed to use an augmented matrix to solve this.

(I don't know how to make the augmented part of the matrix.)

When reducing the matrix, I get a row of zeros, so this means that there is a line of intersection for the planes, so an infinite set of solutions dependent on one parameter.

But the answer says that there is no solution.

I found the line to be:

Thanks!

PS. I hope this is the right section. Sorry Mods if its not
