13-(2-(4/x))=0
Domain of the equation: x))!=0We add all the numbers together, and all the variables
x!=0/1
x!=0
x∈R
-(2-(+4/x))+13=0
We multiply all the terms by the denominator
-(2-(+4+13*x))=0
We calculate terms in parentheses: -(2-(+4+13*x)), so:We get rid of parentheses
2-(+4+13*x)
determiningTheFunctionDomain -(+4+13*x)+2
We add all the numbers together, and all the variables
-(13x+4)+2
We get rid of parentheses
-13x-4+2
We add all the numbers together, and all the variables
-13x-2
Back to the equation:
