y=0.5(100-y)

Solution for y=0.5(100-y) equation:

y=0.5(100-y)

We move all terms to the left:

y-(0.5(100-y))=0

We add all the numbers together, and all the variables

y-(0.5(-1y+100))=0


We calculate terms in parentheses: -(0.5(-1y+100)), so:

0.5(-1y+100)

We multiply parentheses

-0.5y+50

Back to the equation:

-(-0.5y+50)


We get rid of parentheses

y+0.5y-50=0

We add all the numbers together, and all the variables

1.5y-50=0

We move all terms containing y to the left, all other terms to the right

1.5y=50

y=50/1.5

y=33+0.5/1.5
