Let's simplify the given expression step by step:

$x - 2 + x$

1. Combine like terms:
   $x + x - 2$

2. Since $x + x = 2x$, we get:

   $2x - 2$

So, the simplified expression is:
$2x - 2$

Here are five related questions for practice:

1. Simplify: $3x - 5 + 2x + 7$
2. Solve for $x$: $2x - 2 = 10$
3. Expand: $(x - 2)(x + 3)$
4. Factorize: $2x - 2$
5. Evaluate for $x = 4$: $2x - 2$

Tip: When simplifying algebraic expressions, always combine like terms first!
