(55/x+2.2)+(55/x-2.2)=50
We move all terms to the left:
(55/x+2.2)+(55/x-2.2)-(50)=0
Domain of the equation: x+2.2)!=0
x∈R
Domain of the equation: x-2.2)!=0We get rid of parentheses
x∈R
55/x+55/x+2.2-2.2-50=0
We multiply all the terms by the denominator
(2.2)*x-(2.2)*x-50*x+55+55=0
We add all the numbers together, and all the variables
-50x+(2.2)*x-(2.2)*x+110=0
We multiply parentheses
-50x+2.2x-2.2x+110=0
We add all the numbers together, and all the variables
-50x+110=0
We move all terms containing x to the left, all other terms to the right
-50x=-110
x=-110/-50
x=2+1/5
