-12n - 9 = 77 Therefore, -12n = 77+9 = 86 Therefore, n = 86/-12 n = 7.16 recurring (that is, 7.16666..)
4-12n=-7 -12n=-7-4 -12n=-11 12n=11 n=11/12 n=0.916666666666666666...
N=0.
12n = 60divide both sides integers by 12(12/12)n = 60/12n = 5=======check in original equation12(5) = 6060 = 60=======checks
12n = 108 Or n = 108/12

8b = e - 12n, possibly.
If the number is n then 12 times the number is 12*n or 12n.
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
12n + 8 = 11 12n = 3 n = 1/4
Assuming you mean 12m + 12n, you can use the distributive property to take out the common factor 12.
