y=3/8y

Solution for y=3/8y equation:

y=3/8y

We move all terms to the left:

y-(3/8y)=0


Domain of the equation: 8y)!=0

y!=0/1

y!=0

y∈R


We add all the numbers together, and all the variables

y-(+3/8y)=0

We get rid of parentheses

y-3/8y=0

We multiply all the terms by the denominator


y*8y-3=0

Wy multiply elements

8y^2-3=0

a = 8; b = 0; c = -3;
Δ = b2-4ac
Δ = 02-4·8·(-3)
Δ = 96
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:

$\sqrt{\Delta}=\sqrt{96}=\sqrt{16*6}=\sqrt{16}*\sqrt{6}=4\sqrt{6}$
$y_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{6}}{2*8}=\frac{0-4\sqrt{6}}{16}
=-\frac{4\sqrt{6}}{16}
=-\frac{\sqrt{6}}{4}
$
$y_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{6}}{2*8}=\frac{0+4\sqrt{6}}{16}
=\frac{4\sqrt{6}}{16}
=\frac{\sqrt{6}}{4}
