7(x-3)/(x-4)+13/x=-13/x(x-4)
We move all terms to the left:
7(x-3)/(x-4)+13/x-(-13/x(x-4))=0
Domain of the equation: (x-4)!=0
We move all terms containing x to the left, all other terms to the right
x!=4
x∈R
Domain of the equation: x!=0
x∈R
Domain of the equation: x(x-4))!=0We calculate fractions
x∈R
(7(x-3)*x*x(x-4)))/((x-4)*x*x(x-4)))+(13*(x-4)*x(x-4)))/((x-4)*x*x(x-4)))+(-(-13*(x-4)*x)/((x-4)*x*x(x-4)))=0
We can not solve this equation
