2y=5/6y

Solution for 2y=5/6y equation:

2y=5/6y

We move all terms to the left:

2y-(5/6y)=0


Domain of the equation: 6y)!=0

y!=0/1

y!=0

y∈R


We add all the numbers together, and all the variables

2y-(+5/6y)=0

We get rid of parentheses

2y-5/6y=0

We multiply all the terms by the denominator


2y*6y-5=0

Wy multiply elements

12y^2-5=0

a = 12; b = 0; c = -5;
Δ = b2-4ac
Δ = 02-4·12·(-5)
Δ = 240
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:

$\sqrt{\Delta}=\sqrt{240}=\sqrt{16*15}=\sqrt{16}*\sqrt{15}=4\sqrt{15}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{15}}{2*12}=\frac{0-4\sqrt{15}}{24}
=-\frac{4\sqrt{15}}{24}
=-\frac{\sqrt{15}}{6}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{15}}{2*12}=\frac{0+4\sqrt{15}}{24}
=\frac{4\sqrt{15}}{24}
=\frac{\sqrt{15}}{6}
