N is an integer. Write the values of n such that -15 < 3n < 6

Step-by-step explanation:

-15 < 3n                                     ; 3n < 6

Divide both sides by 3            ; Divide both sides by 3

-15/3 < 3n/3                             ; 3n/3 < 6/3

-5 < n                                      : n < 2

         -5 < n < 2

n = {-4, -3, -2, -1, 0 , 1 }

answer: c.
