SOLUTION: 7=ln(5x)+ln(7x-2x)

Question 549533: 7=ln(5x)+ln(7x-2x)
Answer by mananth(16946) (Show Source): You can put this solution on YOUR website!
The first step is to simplify:
7 = ln5x + ln5x
7 = 2ln5x
3.5 = ln5x
Now we try to eliminate the ln from the equation so we raise everything to thepower of e
e^3.5 = e^ln5x
By the identity rule, e^ln5x is equal to 5x
5x = e3.5
5x = 33.1
x = 6.62
