I need help, not quite sure where to start.... Solve the equation: l 3x - 5 l = l 8x - 5 l HELP.... would really like to know how to solve a problem like this : )
hi
r u here or no
Am sorry I didn't see your reply, last night I just gave up and went to sleep..... still need help though..... @Sohal
hi
I wa reading the question and I do believe that there is an answer but it is 0
Thank you for your reply..... have no clue what to do :/
x=0 because on both side -5 is on so you know that only the x matters right its like this 5x+0=7x+0
ok you kind of get it if its equal then the -5 fives on both sides cancel out so you get 3x=8x which 0 would be the only realistic answer got it??
Hello?
Yes am thinking sorry but I input it and it says it's incorrect (0) ...... i have online hw so it tells me right away if it's right or wrong ..... I have unlimited tries but I have yet to figure it out .... I haven't worked one out like this one before with absolute values on both sides ...... @Sohal
wait one sec Ill figure out the problem
ok its undifinde No answer!!!!!!!!!!!
-5x=0 is impossible!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
try that
Undefined or no solution :)
Hello??
Literally tried all of it and still "incorrect" -.- sometimes the software needs a specific answer to count it correct. For example one time the answer for some thing was -5 & 3 (two part answer, not an inverse function) I input it so many ways that were correct and it did not take it till I put [-5,3] .... my professor doesn't expect that but apparently this software has high standards. @Sohal
Thank you for your time anyways ! :)
what website is it?
Its called webwork ......
@Sohal
Haha literally right now I was working on solving x^2-x-20 by factoring and I knew it was x=5 x=-4 ...... i did a similar problem and it didn't take the answer till I put it in parentheses yet this equation didn't take it until it was without parentheses! See I told you ! I like that I have unlimited tries but it's picky on how I write it...... @Sohal
do you still need help?
Yes.... @Anguyennn
ok
so first thing you can do is bring one equation to the other side
whenever it is an absolute value, the number inside will always turn out negative
Ok like subtract -8x+5 to the other side ?
hold on lemme do this on my paper before showing you :P
just give me a sec
Ok ...... i got 3x-8x= 0
hmm I am kind of stuck on this one
I just know that the answer is x=0 and x=10/11
Oh wow, I input it and is says it's correct..... thank you ! But how do you know ? @Anguyennn ??
mathway.com
haha no problem, i apologize for not helping you out properly.
I understand the concept, but it hangs me loose when theres a x in it.
No it's fine ! & Yes it's a bit tricky.... Maybe I should use math way a bit more often haha..... i think if you pay it shows the steps right ? I guess I know why it's so popular for a reason, cause it works haha ! Then again maybe I will just ask my professor during her office hours ..... haha @Anguyennn
alright!good luck :)
Thanks again ! God Bless You ! @Anguyennn
