Solving Ax=b in Parametric Vector Form | System A = 0...-2...9...5, b = 0...0

[Precursor]

Homework Statement

Describe the solution(s) of the system Ax=b in parametric vector form where A =
$$0...-2...9...5$$
$$0...1...2...-6$$

and b =
$$0$$
$$0$$

The attempt at a solution
I got this far:

$$1...0...13...7...0$$
$$0...1...2...-6...0$$

How do I continue to get it into parametric vector form? I only have two leading ones, so does it look like I'll be getting some free variables?

Any suggestions?

Is my work confusing?
