    those two cases will make it < = 0

    so first case + / - , we have (3x + 2) >= 0 and denominator < 0

    Okay, so right now, you can let it behave as though it's an equation and say that (3x+2)/(x-5)= 0 (for simplicity's sake). Then, multiply both sides by x-5, but on both sides it just disappears, leaving you with 3x+2 = 0. Subtract two, and divide by 3, to get x ≤ -2/3, after replacing the "=" with "≤" (in this case, the direction of the inequality doesn't change, so you don't lose any information by converting between the two. Hope that helped

    If you're going to type a response, type it in one swoop, don't just break it up into several just to get your achievements.

    Alright, I think I made a mistake with my sign change from the l.e. to =. Because you had something in the denominator, it does flip to "greater than or equal to", and thus you have x is greater than or equal to -2/3. And, to have the case that cantorset was talking about, you have to have some region where x-5 < 0, which gives you x < 5. So, we now know that x satisfies the expression anywhere in between -2/3 and 5, including -2/3, and excluding 5.

    -2=3x since (3x+2)/(x-5)\[\le\]0 multiply the (x-5) on each side, on the left side it cancels out, on the right side its 0 (0 times any number is 0.) then remove the parenthesis, subtract two, which gets you 3x=-2. you can simplify this further, which will get you a decimal. (which, im also not going to do.)
