The way to solve Order of Operations is by using PEMDAS:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
.
First, we'll solve the parentheses:
4s+300�(10-20)=14
4s+300�(-10)=14
There are no exponents, and no multiplication that can done right now. So, we'll divide 300 and negative 10.
4s+300�(-10)=14
4s+(-30)=14
4s-30=14
Then, we can add 30 to both sides.
4s-30=14
4s=44
Now that the equation is simplified, we can divide both sides by 4.
4s=44
s=11
Since you stated that s was equal to 11, we know that this answer is correct.

Parentheses
Add 30 to both sides
Divide both sides by 4
Thats it! :)

11*4+300/(10-20)=14
44+300/-10=14
44-30=14
addition and subtraction are the very last things you do
