yes it changes
3x-2y <= -6
Multiplying both sides by -1

There are three parts in division operation, namely, the dividend or the no. to be divided, the divisor or the no. that divides the dividend and the quotient or the result of dividing dividend by divisor. Here are the resulting signs in each case:
+ dividend / + divisor = + quotient
+ dividend / - divisor = - quotient
- dividend / + divisor = - quotient
- dividend / - divisor = + quotient
Like signs (+ / + and - / -) = +
Unlike signs (+ / - and - / +) = -
I hope that helps.

Yes, unless the numerator is zero, then the answer is still zero.
