(5/(x+2))-(3/(x+1))+4=0
Domain of the equation: (x+2))!=0
x∈R
Domain of the equation: (x+1))!=0We calculate fractions
x∈R
(5x+5)/((x+2))*x+(-3x-6)/((x+2))*x+4=0
We multiply all the terms by the denominator
(5x+5)+(-3x-6)+4*((x+2))*x=0
We get rid of parentheses
5x-3x+4*((x+2))*x+5-6=0
We add all the numbers together, and all the variables
2x+4*((x+2))*x-1=0
We move all terms containing x to the left, all other terms to the right
2x+4*((x+2))*x=1
