Answer:

4

Explanation:

For this problem, we will need to have knowledge of the order of operations.

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction.

In order from top to bottom.

..................................................................................................................

Using the order of operations we know that first we need to solve what is inside the parentheses.

#22- 2( 13- 7+ 3)#

#22- 2( 6+3)#

#22- 2( 9)#

..................................................................................................................

Now, we are going to do the multiplication, because that is before subtraction on our order of operations.

#22- 2( 9)#

#22- 18#

..................................................................................................................

Now, we just have to do basic subtraction.

#22-18=4#

This brings us to our final answer of 4.
