yes, of course, how careless of me not to notice that you switched the sign.
the correct answer is
x < 18/5
BUT, why do you think we divided by a negative?
4(2x-3) < 3x+6
8x - 12 < 3x + 6
5x < 18
x < 18/5
I decided to be different and subtract the 6 first. That lead me to divide by a negative 5 later in the equation.
You subtracted the 3x first, so you didn't have to divide by a negative at all.
Either way, the sign should be <.
