According to the second posting you meant:
n/(-3+5) > 4
n/2 > 4
multiply both sides by +2
n > 8
if you meant it the way you typed it ...
n/-3+5>4
n/-3 > -1
multiply both sides by -3, inequality sign has to be switched
n < 3
n/(-3+5) > 4
n/2 > 4
multiply both sides by +2
n > 8
if you meant it the way you typed it ...
n/-3+5>4
n/-3 > -1
multiply both sides by -3, inequality sign has to be switched
n < 3

according to "order of operations" ( PEMDAS)
... the division operation occurs before the addition
adding parentheses to clarify ... (n / -3) + 5 > 4
subtracting 5 ... n / -3 > -1
multiplying by -3 (arrow flips) ... n < 3
