n-7=12(n-2)
We move all terms to the left:
n-7-(12(n-2))=0
We calculate terms in parentheses: -(12(n-2)), so:We get rid of parentheses
12(n-2)
We multiply parentheses
12n-24
Back to the equation:
-(12n-24)
n-12n+24-7=0
We add all the numbers together, and all the variables
-11n+17=0
We move all terms containing n to the left, all other terms to the right
-11n=-17
n=-17/-11
n=1+6/11
