Distributive property states that lets you multiply a sum by multiplying each addend separately and then add the products.
i.,e

![52 -[30-14+2x]](https://img.qammunity.org/2017/formulas/mathematics/high-school/uk88r1u3x9g0d6bnr82dvbxcjq09te9c8o.png)
Simplify:
![52 -[16+2x]](https://img.qammunity.org/2017/formulas/mathematics/high-school/mpiknca6go0c0i4pcv5jqvhl188791dmub.png)
Remove the Parenthesis, we get

Then;

Therefore, the simplified form of given expression is,
