In an inequality, if the number is already negative and when I solve it it's still negative do I have to flip the sign?
For example:
3x + 9 < 6
9 9
^
That becomes 15 do I flip the sign?

No, only flip the sign if dividing by or multiplying by a negative number 3x < 15 Now if we divide by say 3 we change sign x > 5 Which makes sense because now if you substitute x into the previous equation 3 multipkied by x being greater than 5 we get a number that is much smaller than 15.
