To solve the equation \( 2\sqrt{2} - 1 - x = 0 \), follow these steps:

### Step 1: Isolate \( x \)
Add \( x \) to both sides of the equation to isolate it:
\[
2\sqrt{2} - 1 = x
\]

### Step 2: Simplify the right-hand side
We already have \( x \) expressed in terms of a constant, so:
\[
x = 2\sqrt{2} - 1
\]

### Final Answer:
\[
x = 2\sqrt{2} - 1
\]

This is the simplified value of \( x \).
