(81+n)>(-3n)
This is the equation
Now plug in possibilities
Anything positive in n will be a negative on the right and that will always be less than the left side
But you put a negative on the left and it will be positive and also will minus from the right
So -1 will work because 80>3
So -2 will work because 79>6
So -3 will work because 78>9
So -4 will work because 77>12
So -5 will work because 76>15
So -6 will work because 75>18
But you see at some point this will not be a true statement so then you answer will be these negative numbers and all positive numbers
