8(0.5-3)=2n-0.25(8-4n)
We move all terms to the left:
8(0.5-3)-(2n-0.25(8-4n))=0
We add all the numbers together, and all the variables
-(2n-0.25(-4n+8))+8(-2.5)=0
We add all the numbers together, and all the variables
-(2n-0.25(-4n+8))-20=0
We calculate terms in parentheses: -(2n-0.25(-4n+8)), so:We get rid of parentheses
2n-0.25(-4n+8)
We multiply parentheses
2n+1n-2
We add all the numbers together, and all the variables
3n-2
Back to the equation:
-(3n-2)
-3n+2-20=0
We add all the numbers together, and all the variables
-3n-18=0
We move all terms containing n to the left, all other terms to the right
-3n=18
n=18/-3
n=-6
