Question

in(1-3x)+3=9

Answer 1

Is it: \(ln(1-3x)+3=9\)?

Answer 2

yes

Answer 3

\(log_e(1-3x)=6\) => \((1-3x) = e^{6}\)
Are you able to do it now?

Answer 4

no :/

Answer 5

1-3x=e^6, try solving that for x

Answer 6

\(-3x = e^{6} - 1 \)

Answer 7

well, looks like you were left in the cold.
from here you divide both sides by -3 to get
\[x=\frac{e^6-1}{-3}\]

Answer 8

\[e^6 = 403.428793\]

Answer 9

now minus 1 and then divide by -3

plus check out the rest of the algebra section. it will help if you search out video lessons and notes and practice problems.

Answer 14

you might want to go right to "what is a logarithm?"

Answer 15

thank you i need as much help conquering this as possible because its just going to get worse so im trying to get a handle on it before its just of hand and besides i hate being dominated by things :D

Answer 16

the more you do and the more you try to practice the better it will get. start saying "it's going to get better if I keep working hard and put in time to practice everyday." that's what I say about everything from teaching to learning to parenting to life...
