12n + 8 = 11 12n = 3 n = 1/4
12n=12 ---- --- 12. 12 N=1
8b = e - 12n, possibly.
what is this answer

It is 12n + 18.
48
4-12n=-7 -12n=-7-4 -12n=-11 12n=11 n=11/12 n=0.916666666666666666...
1, 2, 3, 4, 6, 12, n
GCF of 12 and 18 is 6
Im not sure if this is -12n or just 12n so I will give you both: -12n -19=77 n= -8 12n-19=77 n=8
Assuming you mean 12m + 12n, you can use the distributive property to take out the common factor 12.
12n + 8 = 11 12n = 3 n = 1/4
11n - 12n + 3 = 3 - n
n5n+8n-12n13n-12n = n
