3k+12+3k=6(k+2)
We move all terms to the left:
3k+12+3k-(6(k+2))=0
We add all the numbers together, and all the variables
6k-(6(k+2))+12=0
We calculate terms in parentheses: -(6(k+2)), so:We get rid of parentheses
6(k+2)
We multiply parentheses
6k+12
Back to the equation:
-(6k+12)
6k-6k-12+12=0
We add all the numbers together, and all the variables
=0
