Would the solution be x > 18/5?

yes again!

Hold on... Looking back on this problem, wouldn't it be x < 18/5 since you need to flip the sign when you divide by a negative?

**Reiny**, Tuesday, October 13, 2009 at 5:46pmyes, 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

**Anonymous**, Tuesday, October 13, 2009 at 5:54pmI 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 <.
