Question

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

Answer 1

(-4,-3,-2,-1,0,1,2)

Explanation:

Divide the entire equation by 3 to get n by itself.

-5 < n < 2

Integers are counting numbers (+0)

-4,-3,-2,-1,0,1,2

Answer 2

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 }
