Answer:
n = 10
Step-by-step explanation:
move all terms to the left:
-2-(-(n-8))=0
calculate terms in parentheses: -(-(n-8)), so:
-(n-8)
get rid of parentheses
-n+8
add all the numbers together, and all the variables
-1n+8
go back to the equation:
-(-1n+8)
get rid of parentheses
1n-8-2=0
add all the numbers together, and all the variables
n-10=0
move all terms containing n to the left, all other terms to the right
n=10
