even if i tryed i could't tell you
• jimih67 2009/07/13 15:22:12

5x+3x=8x.
-2y-7y=-9y.

To get a completely numeric answer, you need the values of x and y.

8x = 9y
What are you solving for then? Because all you can come to is 8X = 9y, what are you trying to solve for?

• Keen Tojones 2009/07/13 08:18:15
8x - 9y
• Hitch 2009/07/13 08:09:09
8x = 9y
reallyy after that you should divide by nine so you could get what y=

No math D:
• Lysandra 2009/07/13 07:40:35
8x = 9y
yea... that was easy
• Darling of Ville 2009/07/13 07:36:09
8x = 9y
Basic steps (not condensed) for those who need to see them laid out:
5x - 2y + 3x - 7y = ?

Add 2y to the other side

5x + 3x - 7y = 2y

Add 7y to the other side

5x + 3x = 9y

8x = 9y

close but here is the correct answer::: 8x - 9y = ? You don't know what x or y is so you can't come to a full conclusion....
• Miss Sweety 2009/07/13 07:18:55
8x = 9y
isnt it, 8x=-9y??....lol i became so dumb in maths
• Lixia Miss Sw... 2009/07/13 07:22:33
nun of the numbers are negative... this prob was simple I do plan on a harder on soon and see what answers come up. lol
• Miss Sw... Lixia 2009/07/13 07:23:43
but isnt a negative + negative = a negative?
• Lixia Miss Sw... 2009/07/13 07:27:04
Where are you seeing a negative plus a negative...????
• Miss Sw... Lixia 2009/07/13 07:30:49
lol...you must add the 5x+3x which gives you 8x
then you add the -2y+-7y which gives you -9y
• Lixia Miss Sw... 2009/07/13 07:35:13
The answer is actually not listed above... I am waiting to see if anyone gets it.. And for the last time there are no negative numbers in the answer.

• Lixia bye 2009/07/13 07:17:55
How do you come to your conclusion?
• bye Lixia 2009/07/13 07:19:17
• Lixia bye 2009/07/13 07:21:48
What prob are you looking at??? there is no - in front of the 3.. You must have a migrane...
• bye Lixia 2009/07/13 07:22:47
• Lixia bye 2009/07/13 07:24:57
the prob is 5x - 2y + 3x - 7y = Where is the - before the 3 making it negative?
• bye Lixia 2009/07/13 07:27:29

Math class would do you good.... to make a number negative the - must be close for example -2 not - 2... notice the space.. so if you have a 3 - -2= there for the 2 is then negative but since it is like 3 - 2 = with space there is no negative.. Now do you see.. You are giving me a head ache and if this doesn't explain it to you then you are completly lost and I suggest you go to math.com and study you positives and negatives......
