So if I had an equation or part of one eg, 3x - x, it would be 2x?

I was doing this last week and now I'm drawing blanks on an equation with 2 variables. When you have a constant and a variable + a variable by itself, I forgot if I'm supposed to try to cancel the individual variable, or if I'm supposed to multiply/add it as a "like term". I'm not giving...

For most of the algebra questions I'm working on, I'm doing okay, with an exception here and there. The good news for those who have helped me, I'm getting a handle on the addition and associative properties and finally learned I needed to subtract on both sides of equation. Feeling better about...

I am reading through a introductory algebra textbook and refreshing memory on this topic. In the matter of the Associative Properties, it is giving me the expression 3 + (8+x). (I'm skipping the graphs section because I'm leaving that for my tutor Saturday. But I'm moving to algebra because I...

I just want you to know that I honestly took a lot of time trying to find the factor that goes into both 186, 300. I really did sat here and pulled my hair out wondering what I was missing. As I said, I honestly did not see 2 x 3. I'm trying to figure this on my own since the exam monitors would...

No. I'm sorry I didn't. I just saw 2. I thought I'm supposed to look for single "digit" or number that is common to both N & D. Please don't shoot me for not seeing it. And even if I did see it, I still probably would not have caught on to use it further since I've been programmed to look...

Well, it looks like 2 is prime factor for this. I didn't expect I had to start that low. because as you can see I was busy playing with other combinations similar to what you used in other example. I was trying to work it out with what I was sure method to find LCD, but getting frustrated...

I have been wrecking my brain to find an LCD for both 186 and 300. 30 works for 300 but not for 186-obviously. So what do I do in this situation? I find it baffling someone wrote a problem where only the denominator (300) has an LCD that fits. But I must be missing something other than a few...

Thanks Mark. I have been reviewing basic fractions past 2 weeks and have not worked with larger numbers yet. So that's reason for asking. Examples have been smaller and easier to work with and factor. Still working on exercises from last night. Not done yet. Thank you. I will try to provide...

Hope this is not a stupid question. What is the simplest way to find a factored number that goes into a numerator and denominator if it's 3 digits? Like 240 over 600 or 192 over 268, etc.

Okay, now I see it in clearer terms. So I guess I didn't use proper factorization? I've been programmed to use "lowest" LCD which is why I used 8. So 32 is correct LCD? I want to say I get the gist of what I'm supposed to do as far as finding factor for both numerator and denominator, but it's...

Well part of it does. First I did it backwards. I tried to divide 800/512. And I used 8 as LCD for N/D since I thought it was "lowest LCD". I goofed there. But what do I know. I was in a galaxy long time ago, far, far away since I really had to do this. I also understand it has to be factored...

I'm kinda glad I found this place. Hope it will help. Prepping for state exam and math is on test. Getting stuck on fraction word problem, and probably many more to come. But struggling to figure how to set up this prob: Of 800 adults surveyed, 512 replied that they have used drugs. What...
