#### Explanation:

The associate property of addition means that moving the parenthesis does not change the order of operations or the sum

$x + \left(8 + 3\right) = \left(x + 8\right) + 3$

$\left(x + 8\right) + 3 = \left(4 + 8\right) + 3$

The x and the 4 are in the same place in the equation and everything else is the same therefore.

$x = 4$
