10+12n=3(3+4n)
We move all terms to the left:
10+12n-(3(3+4n))=0
We add all the numbers together, and all the variables
12n-(3(4n+3))+10=0
We calculate terms in parentheses: -(3(4n+3)), so:We get rid of parentheses
3(4n+3)
We multiply parentheses
12n+9
Back to the equation:
-(12n+9)
12n-12n-9+10=0
We add all the numbers together, and all the variables
1!=0
