3m+m+9=2(2m-1)
We move all terms to the left:
3m+m+9-(2(2m-1))=0
We add all the numbers together, and all the variables
4m-(2(2m-1))+9=0
We calculate terms in parentheses: -(2(2m-1)), so:We get rid of parentheses
2(2m-1)
We multiply parentheses
4m-2
Back to the equation:
-(4m-2)
4m-4m+2+9=0
We add all the numbers together, and all the variables
11!=0
