(1/s-9)+1=(9/s-9)
We move all terms to the left:
(1/s-9)+1-((9/s-9))=0
Domain of the equation: s-9)!=0
s∈R
Domain of the equation: s-9))!=0We get rid of parentheses
s∈R
1/s-((9/s-9))-9+1=0
We calculate fractions
s/s^2+(-((9*s)/s^2-9+1=0
We add all the numbers together, and all the variables
s/s^2+(-((+9s)/s^2-9+1=0
We calculate fractions
We do not support espression: s^4
