x+2/3x=190

Solution for x+2/3x=190 equation:

x+2/3x=190

We move all terms to the left:

x+2/3x-(190)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We multiply all the terms by the denominator


x*3x-190*3x+2=0

Wy multiply elements

3x^2-570x+2=0

a = 3; b = -570; c = +2;
Δ = b2-4ac
Δ = -5702-4·3·2
Δ = 324876
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{324876}=\sqrt{4*81219}=\sqrt{4}*\sqrt{81219}=2\sqrt{81219}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-570)-2\sqrt{81219}}{2*3}=\frac{570-2\sqrt{81219}}{6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-570)+2\sqrt{81219}}{2*3}=\frac{570+2\sqrt{81219}}{6}
