2x+x=(12+x)/x

Solution for 2x+x=(12+x)/x equation:

2x+x=(12+x)/x

We move all terms to the left:

2x+x-((12+x)/x)=0


Domain of the equation: x)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

2x+x-((x+12)/x)=0

We add all the numbers together, and all the variables

3x-((x+12)/x)=0

We multiply all the terms by the denominator


3x*x)-((x+12)=0

Wy multiply elements

3x^2=0

a = 3; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·3·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
