10+1/3x=x

Solution for 10+1/3x=x equation:

10+1/3x=x

We move all terms to the left:

10+1/3x-(x)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We add all the numbers together, and all the variables

-1x+1/3x+10=0

We multiply all the terms by the denominator


-1x*3x+10*3x+1=0

Wy multiply elements

-3x^2+30x+1=0

a = -3; b = 30; c = +1;
Δ = b2-4ac
Δ = 302-4·(-3)·1
Δ = 912
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:

$\sqrt{\Delta}=\sqrt{912}=\sqrt{16*57}=\sqrt{16}*\sqrt{57}=4\sqrt{57}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(30)-4\sqrt{57}}{2*-3}=\frac{-30-4\sqrt{57}}{-6}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(30)+4\sqrt{57}}{2*-3}=\frac{-30+4\sqrt{57}}{-6}
