Thank you for the opportunity to help you with your question!

Use the PEMDAS ( parenthesis Exponents mutiplication division addition subtraction)

We have only parenthesis and subtraction 

First simplify terms in innermost parenthesis ( ) 6w-8w = -2w

expression becomes w - {5w-[6w-(-2w)]} 

Again simplify the terms in innermost parenthesis [ ] 6w-(-2w) = 8w

expression becomes w-{5w-8w}

simplify terms in parenthesis { } 5w-8w = -3w

expression becomes w-(-3w) = 4w


Please let me know if you need any clarification. I'm always happy to answer your questions.

I have a  new question. Here it goes. 


Henry is paid $34 for each of the first 40 lawns he mows and $42 for every lawn he mows after that. If he mows 55 lawns and pays for $156 in gas, how much is his take-home pay?

Henry mowed 55 lawns.

First 40 lawn =>$34 per lawn             after that $42 per lawn 

He mowed 55 lawns so number of lawns he mowed for price $42 = 55 - 40 = 15 

Total money earned from mowing the lawns = 34 X40 + 42 X 15 = $1990

He paid $156 for gas .

His take home pay = 1990 - 156 =$1,834
