4/3-x+1/x+9=5/3-x
check my response to the same question
http://www.jiskha.com/display.cgi?id=1247009457
Is it -3 or -3/26? I ran this problem through 2 calculators online and they both came up with -3/26? Can you explain why its only -3? Thanks
I haven't got a clue how both you and Crystal came up with -3/26
Both Marth and I gave you the way to solve this question, assuming that you meant
4/(3-x) + 1/(x+9) = 5/(3-x)
Ok, you solved it the way it stands, as
(4/3) - x + (1/x) + 9 = (5/3) - x
yes, that would be x = -3/26
check your text, is that the way it is actually typed ??
This discussion only illustrates how important it is to correctly establish the order of operation with brackets.
It is typed as follows:
4 1 5
--- + --- = ---
3-x x+9 3-x
So is the answer -3/26 or just -3?
That got all messed up. 4 is on top of the 3-x, 1 is over x+9, and 5 is over 3-x respectively So is the answer still -3 or -3/26? Thank you!
just as I thought !!!
obviously x=-3
Why don't you go back to the post I linked to
There you will see a proper solution and verification of the answer of x = -3
What did i do wrong? I am confused to the fact that -3 is the answer and not -3/26?
Are you not familiar with the proper order of operation ?
you did not follow the correct order.
BEDMAS
B - brackets first
E - exponents
D
M - division/multiplication in the order they occur.
A
S - addition/subtraction in the order they occur
I repeat...
take a look at how to properly solve it in the linked post by both me and Marth
