187-(3-8(1+4n))=0
We add all the numbers together, and all the variables
-(3-8(4n+1))+187=0
We calculate terms in parentheses: -(3-8(4n+1)), so:We get rid of parentheses
3-8(4n+1)
determiningTheFunctionDomain -8(4n+1)+3
We multiply parentheses
-32n-8+3
We add all the numbers together, and all the variables
-32n-5
Back to the equation:
-(-32n-5)
32n+5+187=0
We add all the numbers together, and all the variables
32n+192=0
We move all terms containing n to the left, all other terms to the right
32n=-192
n=-192/32
n=-6
