-1
Step-by-step explanation:
The required relation is ...
7n = n^2 -8
0 = n^2 -7n -8 . . . . put in standard form
0 = (n -8)(n +1) . . . . factor
Solutions are n=8 and n=-1.
The negative solution is -1.
Answer:
-3
Step-by-step explanation:
The statement is,
→ Sum of 9 and -16 increased by 4
The equation will be,
→ {9 +(-16)} + 4
