Question

Is the LCD of this equation
-5/(3x-9)+4/(x-3)=5/6
18(x-3) or 6(x-3)

Answer 1

This should clear it up a little bit
\[\frac{-5}{(3x-9)}+\frac{4}{(x-3)}=\frac{5}{6}\]

Answer 2

3*x-9

Answer 3

Am still lost because when 3x-9 is factored it is 3(x-3)... and you have to factor the 6 in 5/6 to 3*2 and when you find the common factor in them shouldn't it be 3*2(x-3)...?

Answer 4

well for the lhs it is 3x-9

Answer 5

Umm, how did you get that timo?

Answer 6

but if you set equation = to 0
-5/(3*x-9)+4/(x-3)-5/6=0
lhs common denom is


6*x-18

Answer 7

Oh, okay I see where your coming from... Idk which one to go with... but thanks so much!!!

Answer 8

LOL ask around also cuzz I am not exactly sure :P

Answer 9

okay... thanks

Answer 10

it also simplifies to this

7/(3*(x-3)) = 5/6
