Solution for ln(2x+1)+ln(x-9)-2lnx=0 equation: 


Simplifying
ln(2x + 1) + ln(x + -9) + -2lnx = 0

Reorder the terms:
ln(1 + 2x) + ln(x + -9) + -2lnx = 0
(1 * ln + 2x * ln) + ln(x + -9) + -2lnx = 0
(1ln + 2lnx) + ln(x + -9) + -2lnx = 0

Reorder the terms:
1ln + 2lnx + ln(-9 + x) + -2lnx = 0
1ln + 2lnx + (-9 * ln + x * ln) + -2lnx = 0
1ln + 2lnx + (-9ln + lnx) + -2lnx = 0

Reorder the terms:
1ln + -9ln + 2lnx + lnx + -2lnx = 0

Combine like terms: 1ln + -9ln = -8ln
-8ln + 2lnx + lnx + -2lnx = 0

Combine like terms: 2lnx + lnx = 3lnx
-8ln + 3lnx + -2lnx = 0

Combine like terms: 3lnx + -2lnx = 1lnx
-8ln + 1lnx = 0

Solving
-8ln + 1lnx = 0
