1/6x=2x-11

Solution for 1/6x=2x-11 equation:

1/6x=2x-11

We move all terms to the left:

1/6x-(2x-11)=0


Domain of the equation: 6x!=0

x!=0/6

x!=0

x∈R


We get rid of parentheses

1/6x-2x+11=0

We multiply all the terms by the denominator


-2x*6x+11*6x+1=0

Wy multiply elements

-12x^2+66x+1=0

a = -12; b = 66; c = +1;
Δ = b2-4ac
Δ = 662-4·(-12)·1
Δ = 4404
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:

$\sqrt{\Delta}=\sqrt{4404}=\sqrt{4*1101}=\sqrt{4}*\sqrt{1101}=2\sqrt{1101}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(66)-2\sqrt{1101}}{2*-12}=\frac{-66-2\sqrt{1101}}{-24}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(66)+2\sqrt{1101}}{2*-12}=\frac{-66+2\sqrt{1101}}{-24}
