Question

Simplify the following by removing the parentheses and combining like terms.. (pic in comments)

Answer 1

Do you want to give it a whirl and see how you do?
Or, would you prefer another explanation by parts before you try one on your own?
It's your call.

Answer 2

Okay, well obviously the 3+3 would be 6.. so then it would be.. 6(2t-4) and you would multiply that by both of them right? the 2 and the.. would that be -4? (that's where i usually get mixed up lol)

Answer 3

3 + 3 ( 2t - 4) - 3 ( 4t + 8) - 6 = ?

Answer 4

3 + 3 ( 2t - 4) - 3 ( 4t + 8) - 6 =

3 + 6t - 12 -12t -24 - 6 =

Answer 5

@kaela_stanley

3 + 3 ( 2t - 4) does not mean 3 + 3.

3 and then 3*(2t -4) are not like terms.

That second 3 in front of the (2t -4) is not really a 3.

That second 3 is really 6t - 12.

Answer 6

Ah okay, that makes sense now.. so the second one is pretty much to multiply with the 2 and the -4 then the first one stays there until we combine the like terms, right?

Answer 7

Yes with one exception.

so the second one is pretty much to multiply with the **2t** and the -4

To multiply with the 2t. Remember, 2 and then 2t are as different as day and night.

Answer 8

So now with the.. 3 + 6t - 12 -12t -24 - 6 =
combined..
Would be..
-6t + would that be -15? or no..
-6t-15 ? Because when it's a negative you subtract it instead of adding it?

Answer 9

3 -------------------> 3
+ 3 ( 2t - 4) -----------> 6t - 12
- 3 ( 4t + 8) -----------> -12t -24
- 6 -------------------> -6
-----------------------------------------

3 -12 -24 -6 = - 39

6t - 12t = - 6t

================

-39 - 6t or as we usually say ---> -6t - 39

Answer 10

Ah! I completely missed the -24 in there.. lol

Answer 11

Would you consider posting what you get for these 9 problems.

Answer 12

Let's see if we can pinpoint where the confusion begins.

If you only have time for a few of the problems, that's okay. It's up to you.

Answer 13

Okay, 1. -2f+5
2. -8t+15
3. Okay I'm not sure about these.. (I didn't do this one or..8?) Because I'm not sure how to solve them exactly.. for this one would it be like 1s-2s?
4. -21b-27
6. -1c+6? (Wasn't entirely sure on this one)
7. 12r-6
8. (I'll finish this one after I'm clear about three)
9. 1b+7? Now I wasn't 100% sure on this one either.. since it's 1b would it just be b+7? or keep the one?

Answer 15

You can make question and answer sheets here:

Answer 16

On #3, s - 2s is 1s - 2s = -1s or just -s.

One s minus two s leaves you short one s, so -s is the result.

Answer 17

#6 is similar

8c -9c + 6 = -1c + 6 or just -c + 6.

8 of the c were here and 9 of the c left, leaving us short one c or -1c which is -c.

The 6 does not end in c. It is an unlike term.

So, the answer is -c + 6

Answer 18

Ah, okay well that makes sense now.. I wasn't completely sure about canceling out the -1 but I was pretty sure that you would.

Answer 19

And for 9, I did re-do that one and like the 3+3 I forgot to carry the 6 over and add it to the 7..

Answer 20

It helps to write down the steps. I do because it is easy to lose a term.

What about #2?

Answer 21

Okay for that one.. for the 2(-4p-3) For the first part I got.. -8p-6+9? then -8p+3 I just re-did it and wrote it down on paper solving the steps and this time I did get it right.. I have no idea what I did the first time.. lol

Answer 22

2(-4p-3) For the first part I got.. -8p-6+9? Yes
which is -8p + 3

I write all the steps down on paper and especially so when I am helping someone on OS.

Answer 23

What about the other problems? Shall we talk about them?
Also, I can post a few more.

Answer 24

So do i, I can say for the most part actually doing these few problems with your help I do understand them a lot better now.. I did a few on my homework (My class is online my homework I do the problem, submit the answer and I can check my answer like twice and if i get it wrong it resets the problem) But I did do a few on my own after you've helped me and I did get them right.. lol And.. the problems.. 1,4 and 7.. I didn't really have any problems with after knowing how to solve them now. :p

Answer 25

Are you up for a 3 problem nightcap?

If so, I am.

I will attach them here.

Answer 26

And, maybe tomorrow we can work on simplification problems with two variables.
Or, your assigned problems. Whatever helps you is what we will do.
And, I appreciate your willingness to hang in there and do these problems.
I know how frustrating it can be. But, look at the progress you've made.

Answer 27

Sounds good to me.. and yeah it is very frustrating.. especially after you do math for so long.. /: But it was worth it at least I pretty much know how to solve them now.. for the most part.. I've had a few minor mistakes. but I'm getting better lol.

Answer 28

Okay, for the first one I got.. -21x-24

2. -27x+16

3. -48n-63

Answer 29

That is what I got for all three of them Congrats to you.

Answer 30

Thanks so much for helping me actually understand how to solve them. :)

Answer 31

You are welcome. Catch you soon for the two variable type problems or your other math work.
