1/x+1/(x+1)=9/20

Solution for 1/x+1/(x+1)=9/20 equation:

1/x+1/(x+1)=9/20

We move all terms to the left:

1/x+1/(x+1)-(9/20)=0


Domain of the equation: x!=0

x∈R



Domain of the equation: (x+1)!=0

We move all terms containing x to the left, all other terms to the right

x!=-1

x∈R


We add all the numbers together, and all the variables

1/x+1/(x+1)-(+9/20)=0

We calculate fractions


(-9x^2*()/(20x^2+20x)+(20x+20)/(20x^2+20x)+40x/(20x^2+20x)=0


We calculate terms in parentheses: +(-9x^2*()/(20x^2+20x)+(20x+20)/(20x^2+20x)+40x/(20x^2+20x), so:

-9x^2*()/(20x^2+20x)+(20x+20)/(20x^2+20x)+40x/(20x^2+20x

We calculate fractions

We do not support expression: x^3
