Answer:

$x = 0$

Step-by-step explanation:

Given

Represent the number with x.

So:

$2 + x + x + x + x + x + x + x + x + x + x = 2$

$2 + 10x = 2$

We want to solve for x

Subtract both sides by 2

$2 - 2 + 10x = 2 - 2$

$10x = 0$

Solve for x

$x = \frac{0}{10}$

$x = 0$

No other number aside 0, satisfy the property.
