Question

Find the potential solution to the equation
log4(2 – x) = log4(–5x – 18).

Answer 1

\[\log_4(2 – x) = \log_4(–5x – 18).\]
for example log_4 = b
\[\huge\rm b(2 – x) = b(–5x – 18).\] how would you solve this for x ?

Answer 2

hint: UNlog both sides

Answer 3

so i should distribute the 4 into each?

Answer 4

4 ?? 4 is base of log
both sides llog bases are same

Answer 5

in other words divide log_4 both side

Answer 6

ohh thanks

Answer 7

yep then just simple algebra stuff :-D
