1/2*y=6

Solution for 1/2*y=6 equation:

1/2*y=6

We move all terms to the left:

1/2*y-(6)=0


Domain of the equation: 2*y!=0

y!=0/1

y!=0

y∈R


We multiply all the terms by the denominator


-6*2*y+1=0

Wy multiply elements

-12y*y+1=0

Wy multiply elements

-12y^2+1=0

a = -12; b = 0; c = +1;
Δ = b2-4ac
Δ = 02-4·(-12)·1
Δ = 48
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{48}=\sqrt{16*3}=\sqrt{16}*\sqrt{3}=4\sqrt{3}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{3}}{2*-12}=\frac{0-4\sqrt{3}}{-24}
=-\frac{4\sqrt{3}}{-24}
=-\frac{\sqrt{3}}{-6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{3}}{2*-12}=\frac{0+4\sqrt{3}}{-24}
=\frac{4\sqrt{3}}{-24}
=\frac{\sqrt{3}}{-6}
