Question

n/-3 + 5 > 4=

Have to explain all of the steps...every time I do it I come out with a different answer.

Please I am totally lost on this one...Thank you.

Answer 1

so, why don't you show us what you did?

If you meant

n/-3 + 5 >= 4
just work it as usual: subtract 5
n/-3 >= -1
Now multiply by -3 and change direction
n <= 3

The reason you change direction is just a shortcut for moving things around by addition and subtraction:

n/-3 >= -1
-n/3 >= -1
0 >= -1 + n/3
1 >= n/3
That is just the same as
n/3 <= 1
n <= 3
