-2/3x+4x-(-3)=0


Domain of the equation: 3x!=0

x!=0/3

x!=0

x∈R


We add all the numbers together, and all the variables

4x-2/3x+3=0

We multiply all the terms by the denominator


4x*3x+3*3x-2=0

Wy multiply elements

12x^2+9x-2=0

a = 12; b = 9; c = -2;
Δ = b2-4ac
Δ = 92-4·12·(-2)
Δ = 177
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(9)-\sqrt{177}}{2*12}=\frac{-9-\sqrt{177}}{24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(9)+\sqrt{177}}{2*12}=\frac{-9+\sqrt{177}}{24}
