Question 1000146: Determine the value(s) of x such that log_x(x−7)+log_x(x)=1. Separate multiple answers with a comma. (Hint: Consider the domain of a logarithmic function.)
*underscore means base for example log_4 means log base 4.
Thanks!

----------
logx[x(x-7)] = 1
----
x^2-7x = x
----
x^2 - 8x = 0
---
x(x-8) = 0
----
Acceptable answer:: x = 8
