-0.2(1-y)=2(4+0.1y)

Solution for -0.2(1-y)=2(4+0.1y) equation:

-0.2(1-y)=2(4+0.1y)

We move all terms to the left:

-0.2(1-y)-(2(4+0.1y))=0

We add all the numbers together, and all the variables

-0.2(-1y+1)-(2(0.1y+4))=0

We multiply parentheses

0.2y-(2(0.1y+4))-0.2=0


We calculate terms in parentheses: -(2(0.1y+4)), so:

2(0.1y+4)

We multiply parentheses

0y+8

We add all the numbers together, and all the variables

y+8

Back to the equation:

-(y+8)


We get rid of parentheses

0.2y-y-8-0.2=0

We add all the numbers together, and all the variables

-0.8y-8.2=0

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

-0.8y=8.2

y=8.2/-0.8

y=-10+0.2/0.8
