Question

solve for x: log(1-x) - log(8+x) = 1

I got this so far: (1-x/8+x) = 10

Answer 1

multiply both sides by (8+x) and post what you get.

Answer 2

ok. (8/16+x^2) = 80+10x

Answer 3

thats wrong i know it

Answer 4

yup, it is catastrophically wrong.

Answer 5

ok im retarded maybe its the caffeine buz

Answer 6

please explain why u have to multiply by 8+x on both. why not 1-x on both?

Answer 7

always be clear in what you are writing. use brackets to make your meaning clear.
it is (1-x)/(8+x) = 10
multiply by (8+x) on both sides
(1-x)*(8+x)/(8+x) = 80+10x
the (8+x) cancels out in the numerator and denomiator on the left hand side, leaving
1-x = 80+10x.
I trust you can take it from there?

Answer 8

Yes thanx

Answer 9

x=79/11

Answer 10

you multiply by 8+x since you want to cancel it out from the denominator.

Answer 11

- negative

Answer 12

yes

Answer 13

dude i just noticed, im so dumb. haha
