 # Title: school, and newbs

1. ## school, and newbs

Okay well first is the school: I need help finishing some of my math homework.....
Im too lazy to think right now cuz i wanna enjoy my last day of winter break( tomorrow i have to go to school -cries-)

20.) 6x+3=4x+11

21.) 6x-3=11

22.) -3x+5=7

_______________________________________________________________

Now newbs:
In tcg whenever i play like casual games newbs keep adding me, everytime i clicked no..
People say there is a ignore button in tcg.. well idk where it is
could somebody help me? 2. ## Re: school, and newbs

Right click on them and you can ignore Regards. 3. ## Re: school, and newbs

20. x=4
21. x=7/3
22. x=-2/3
I miss easy Algebra! >.< 4. ## Re: school, and newbs Originally Posted by Princess Celestina 20. x=4

Or in decimals:

21. 6x=11+3, 6x=14, 14:6 = 2,33 (or 7/3 in fractions as Celestina pointed out)
22. -3x = 7-5, -3x = 2, 2: (-3) = -0,67 (or 2/3) 5. ## Re: school, and newbs

I can Kinda help you on the math... my brain has melted a little because of no school O_o
I can do 20 and 22 but not 21 yet O_O (I kinda forget how to do 21)
I miss really easy math(6*15)
and to Celes and Keith its 1.33 on 21 because you forgot to do -3 instead of 3(I think that is how you do it....)
Edit: I now know how to do 21 Last edited by Abiagail Coralmusic; 01-02-2011 at 01:05 PM. 6. ## Re: school, and newbs

6x+3=4x+11
Minus 3
Plus 4x
Divide by 10
Wat Get?
x = 0.8

6x-3=11
Plus 3
Divide by 6
Wat get?
x = 2.3 (repeating of course)

-3x+5=7
Minus 5
Divide by -3
Wat get?
x = -0.6 (repeating of course)

Don't divide by zero. D: And this was done in like a minute, lol.

And apparently I need to go relearn how to make tables on this forum.

Princess, did I do it wrong? >_> I haven't had mathematics for awhile. 7. ## Re: school, and newbs Originally Posted by EatMonkies 6x+3=4x+11

Hmm? The last two are good, but how did you get 0.8 in the first? It's 0.25 here.

6x+3=4x+11
6x-4x=11-3 (the unknown value goes to the left and changes from positive to negative, and the known value goes to the right changing from positive to negative)
2x=8
2:8 = 0.25 8. ## Re: school, and newbs

My teacher prefers fractions; so, I showed you the answer in fraction form. Every teacher has a different preference.  9. ## Re: school, and newbs Originally Posted by Keith Silvernight Hmm? The last two are good, but how did you get 0.8 in the first? It's 0.25 here.

6x+3=4x+11
6x-4x=11-3 (the unknown value goes to the left and changes from positive to negative, and the known value goes to the right changing from positive to negative)
2x=8
2:8 = 0.25
Whee, I simply moved the 4x to the left instead of balancing the scales. lol D: 10. ## Re: school, and newbs

Here's how I do it:
6x+3=4x+11
Subtract 3 on both sides.
Subtract 4x on both sides.
+3, -3 on the left cancels out.
+4x, -4x on the right cancels out.
2x=8
Divide by 2 on both sides.
2 divided by 2 is 1.
8 divided by 2 is 4.
(1)x=4

21. 6x-3=11
-3; +3 on the left cancel out.
11 plus 3 equals 14.
6x=14
Divide by 6 on each side.
6 divided by 6 is 1.
14 divided by 6? Can't do that. It can either be a mixed number or an improper fraction.
(1)x=7/3 OR 2 1/3

22. -3x+5=7
Subtract 5 on both sides.
+5, -5 on the left cancel out.
7 minus 5 equals 2.
-3x=2
Divide by -3 on both sides.
-3 divided by -3 equals a +1 because a negative divided/multiplied by a negative equals a positive.
2 divided by -3? Can't do that. So, it's a fraction.
(1)x=-2/3

Sorry it took awhile to reply. I was afk. =P
