1/2=1/4(8-y)

Solution for 1/2=1/4(8-y) equation:

1/2=1/4(8-y)

We move all terms to the left:

1/2-(1/4(8-y))=0


Domain of the equation: 4(8-y))!=0

y∈R


We add all the numbers together, and all the variables

-(1/4(-1y+8))+1/2=0

We calculate fractions


()/(-8y)+(4y(-)/(-8y)=0


We calculate terms in parentheses: +(4y(-)/(-8y), so:

4y(-)/(-8y

We add all the numbers together, and all the variables

4y0/(-8y

We multiply all the terms by the denominator


4y0

We add all the numbers together, and all the variables

4y

Back to the equation:

+(4y)


We add all the numbers together, and all the variables

4y+()/(-8y)=0

We multiply all the terms by the denominator


4y*(-8y)+()=0

We add all the numbers together, and all the variables

4y*(-8y)=0

We multiply parentheses

-32y^2=0

a = -32; b = 0; c = 0;
Δ = b2-4ac
Δ = 02-4·(-32)·0
Δ = 0
Delta is equal to zero, so there is only one solution to the equation
