Solution for ln(x-8)+ln(x+1)=2lnx equation: 


Simplifying
ln(x + -8) + ln(x + 1) = 2lnx

Reorder the terms:
ln(-8 + x) + ln(x + 1) = 2lnx
(-8 * ln + x * ln) + ln(x + 1) = 2lnx
(-8ln + lnx) + ln(x + 1) = 2lnx

Reorder the terms:
-8ln + lnx + ln(1 + x) = 2lnx
-8ln + lnx + (1 * ln + x * ln) = 2lnx
-8ln + lnx + (1ln + lnx) = 2lnx

Reorder the terms:
-8ln + 1ln + lnx + lnx = 2lnx

Combine like terms: -8ln + 1ln = -7ln
-7ln + lnx + lnx = 2lnx

Combine like terms: lnx + lnx = 2lnx
-7ln + 2lnx = 2lnx

Add '-2lnx' to each side of the equation.
-7ln + 2lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
-7ln + 0 = 2lnx + -2lnx
-7ln = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
-7ln = 0

Solving
-7ln = 0

Solving for variable 'l'.

Move all terms containing l to the left, all other terms to the right.

Divide each side by '-7'.
ln = 0

Simplifying
ln = 0
