2(n-1)+4n=2(3n-10)
We move all terms to the left:
2(n-1)+4n-(2(3n-10))=0
We add all the numbers together, and all the variables
4n+2(n-1)-(2(3n-10))=0
We multiply parentheses
4n+2n-(2(3n-10))-2=0
We calculate terms in parentheses: -(2(3n-10)), so:We add all the numbers together, and all the variables
2(3n-10)
We multiply parentheses
6n-20
Back to the equation:
-(6n-20)
6n-(6n-20)-2=0
We get rid of parentheses
6n-6n+20-2=0
We add all the numbers together, and all the variables
18!=0
