x/3x=6+2x

Solution for x/3x=6+2x equation:

x/3x=6+2x

We move all terms to the left:

x/3x-(6+2x)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We add all the numbers together, and all the variables

x/3x-(2x+6)=0

We get rid of parentheses

x/3x-2x-6=0

We multiply all the terms by the denominator


x-2x*3x-6*3x=0

Wy multiply elements

-6x^2+x-18x=0

We add all the numbers together, and all the variables

-6x^2-17x=0

a = -6; b = -17; c = 0;
Δ = b2-4ac
Δ = -172-4·(-6)·0
Δ = 289
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$\sqrt{\Delta}=\sqrt{289}=17$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-17)-17}{2*-6}=\frac{0}{-12}
=0
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-17)+17}{2*-6}=\frac{34}{-12}
=-2+5/6
