-2x+5/6x=3

Solution for -2x+5/6x=3 equation:

-2x+5/6x=3

We move all terms to the left:

-2x+5/6x-(3)=0


Domain of the equation: 6x!=0

x!=0/6

x!=0

x∈R


We multiply all the terms by the denominator


-2x*6x-3*6x+5=0

Wy multiply elements

-12x^2-18x+5=0

a = -12; b = -18; c = +5;
Δ = b2-4ac
Δ = -182-4·(-12)·5
Δ = 564
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:

$\sqrt{\Delta}=\sqrt{564}=\sqrt{4*141}=\sqrt{4}*\sqrt{141}=2\sqrt{141}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-18)-2\sqrt{141}}{2*-12}=\frac{18-2\sqrt{141}}{-24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-18)+2\sqrt{141}}{2*-12}=\frac{18+2\sqrt{141}}{-24}
