(3)/(x+1)+(4)/(x)=(7)/(x+2)

Solution for (3)/(x+1)+(4)/(x)=(7)/(x+2) equation:

(3)/(x+1)+(4)/(x)=(7)/(x+2)

We move all terms to the left:

(3)/(x+1)+(4)/(x)-((7)/(x+2))=0


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



Domain of the equation: x!=0

x∈R



Domain of the equation: (x+2))!=0

x∈R


We calculate fractions


(3x^2*()/((x+1)*x*(x+2)))+(4*(x+1)*(x+2)))/((x+1)*x*(x+2)))+(-(7*(x+1)*x)/((x+1)*x*(x+2)))=0


We calculate terms in parentheses: +(3x^2*()/((x+1)*x*(x+2))), so:

3x^2*()/((x+1)*x*(x+2))

We multiply all the terms by the denominator


3x^2*()

Back to the equation:

+(3x^2*())



We calculate terms in parentheses: +(4*(x+1)*(x+2)))/((x+1)*x*(x+2)))+(-(7*(x+1)*x)/((x+1)*x*(x+2))), so:

4*(x+1)*(x+2)))/((x+1)*x*(x+2)))+(-(7*(x+1)*x)/((x+1)*x*(x+2))

We add all the numbers together, and all the variables

4*(x+1)*(x+2)))/((x+1)*x*(x+2)))+(-(7*(x+1)*x)/((x+1)*x*(x

We multiply all the terms by the denominator


4*(x+1)*(x+2)))+1*x*x*((x+2))+(-(7*x*((x+1)*x)+1*x*x*((x

Wy multiply elements

x^3*x+4*(x+1)*(x+2)))+1*x*x*((x+2))+(-(7*x*((x+1)*x)

We do not support expression: x^3
