4(r+4)=7-2(1-2r)
We move all terms to the left:
4(r+4)-(7-2(1-2r))=0
We add all the numbers together, and all the variables
4(r+4)-(7-2(-2r+1))=0
We multiply parentheses
4r-(7-2(-2r+1))+16=0
We calculate terms in parentheses: -(7-2(-2r+1)), so:We get rid of parentheses
7-2(-2r+1)
determiningTheFunctionDomain -2(-2r+1)+7
We multiply parentheses
4r-2+7
We add all the numbers together, and all the variables
4r+5
Back to the equation:
-(4r+5)
4r-4r-5+16=0
We add all the numbers together, and all the variables
