(F)=F+1/F-3
We move all terms to the left:
(F)-(F+1/F-3)=0
Domain of the equation: F-3)!=0We get rid of parentheses
F∈R
F-F-1/F+3=0
We multiply all the terms by the denominator
F*F-F*F+3*F-1=0
We add all the numbers together, and all the variables
3F+F*F-F*F-1=0
Wy multiply elements
F^2-1F^2+3F-1=0
We add all the numbers together, and all the variables
3F-1=0
We move all terms containing F to the left, all other terms to the right
3F=1
F=1/3
F=1/3
