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.
