600=x+1/3x

Solution for 600=x+1/3x equation:

600=x+1/3x

We move all terms to the left:

600-(x+1/3x)=0


Domain of the equation: 3x)!=0

x!=0/1

x!=0

x∈R


We add all the numbers together, and all the variables

-(+x+1/3x)+600=0

We get rid of parentheses

-x-1/3x+600=0

We multiply all the terms by the denominator


-x*3x+600*3x-1=0

Wy multiply elements

-3x^2+1800x-1=0

a = -3; b = 1800; c = -1;
Δ = b2-4ac
Δ = 18002-4·(-3)·(-1)
Δ = 3239988
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:

$\sqrt{\Delta}=\sqrt{3239988}=\sqrt{4*809997}=\sqrt{4}*\sqrt{809997}=2\sqrt{809997}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1800)-2\sqrt{809997}}{2*-3}=\frac{-1800-2\sqrt{809997}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1800)+2\sqrt{809997}}{2*-3}=\frac{-1800+2\sqrt{809997}}{-6}
