its actually n+12
explanation
5n-3{6+2(n-1)}=
5n-3(6+2n-2)=
5n-18-6n+6=
-n-12= n+12

5n - 3 [ 6 + 2(n - 1)]
5n - 3 [ 6 + 2n - 2]
5n - 3 [ 4 + 2n]
5n - 12 - 6n
-n - 12

5n-3[6+2(n-1)]=0
5n-3(6+2n-2)=0
5n-3(2n+4)=0
5n-6n-12=0
-n-12=0|(-1)
n+12=0
n= -12
Verification:
If n= -12
So: 5*(-12)-3[6+2(-12-1)=0
-60-3(6-24-2)=0
-60-18+72+6=0
12-18+6=0
-6+6=0
