Answer:
The number 3 makes this statement true.

Explanation:
Given the equation:

Using the order of operations, we can evaluate the terms in the parentheses through the process of multiplication:

Multiply the terms on both sides of the equation:

Finally, divide both sides of the equation by the coefficient of
, which is
:


-
Let's check our work by substituting the solved
value for



Since both sides of the equation are equal to each other, our solution is correct!
