Question

What is `x` in `x+ ( 8+ 3) = ( 4+ 8) + 3`?

Answer 1

4

Explanation:

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

`x + ( 8 + 3) = ( x + 8 ) + 3`

`( x + 8 ) + 3 = ( 4 +8 ) + 3`

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

`x = 4`
