4-12n=-7 -12n=-7-4 -12n=-11 12n=11 n=11/12 n=0.916666666666666666...
12n=12 ---- --- 12. 12 N=1
8b = e - 12n, possibly.

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
2/3
-12n - 9 = 77 Therefore, -12n = 77+9 = 86 Therefore, n = 86/-12 n = 7.16 recurring (that is, 7.16666..)
N=0.
n = 0.25
13n-12n=14+10 13n-12n=1n 1n=n n=14+10 14+10=24 n=24 so the answer is n=24
12n-24 = -14n+28 ADD 24 TO BOTH SIDES 12n = -14n+52 ADD 14n TO BOTH SIDES 26n = 52 DIVIDE BOTH SIDES BY 26 n = 2
