We move all terms to the left:

2/3x-16-(2x-6)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We get rid of parentheses

2/3x-2x+6-16=0

We multiply all the terms by the denominator


-2x*3x+6*3x-16*3x+2=0

Wy multiply elements

-6x^2+18x-48x+2=0

We add all the numbers together, and all the variables

-6x^2-30x+2=0

a = -6; b = -30; c = +2;
Δ = b2-4ac
Δ = -302-4·(-6)·2
Δ = 948
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:

$\sqrt{\Delta}=\sqrt{948}=\sqrt{4*237}=\sqrt{4}*\sqrt{237}=2\sqrt{237}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-30)-2\sqrt{237}}{2*-6}=\frac{30-2\sqrt{237}}{-12}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-30)+2\sqrt{237}}{2*-6}=\frac{30+2\sqrt{237}}{-12}
