1-0,5(1-y)=-0,2(y+1)

Solution for 1-0,5(1-y)=-0,2(y+1) equation:

1-0.5(1-y)=-0.2(y+1)

We move all terms to the left:

1-0.5(1-y)-(-0.2(y+1))=0

We add all the numbers together, and all the variables

-0.5(-1y+1)-(-0.2(y+1))+1=0

We multiply parentheses

0.5y-(-0.2(y+1))-0.5+1=0


We calculate terms in parentheses: -(-0.2(y+1)), so:

-0.2(y+1)

We multiply parentheses

-0.2y-0.2

Back to the equation:

-(-0.2y-0.2)


We add all the numbers together, and all the variables

0.5y-(-0.2y-0.2)+0.5=0
