Solution for ln(x)+ln(x+2)=ln(15) equation: 


Simplifying
ln(x) + ln(x + 2) = ln(15)

Multiply ln * x
lnx + ln(x + 2) = ln(15)

Reorder the terms:
lnx + ln(2 + x) = ln(15)
lnx + (2 * ln + x * ln) = ln(15)
lnx + (2ln + lnx) = ln(15)

Reorder the terms:
2ln + lnx + lnx = ln(15)

Combine like terms: lnx + lnx = 2lnx
2ln + 2lnx = ln(15)

Reorder the terms for easier multiplication:
2ln + 2lnx = 15ln

Solving
2ln + 2lnx = 15ln

Solving for variable 'l'.

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

Add '-15ln' to each side of the equation.
2ln + -15ln + 2lnx = 15ln + -15ln

Combine like terms: 2ln + -15ln = -13ln
-13ln + 2lnx = 15ln + -15ln

Combine like terms: 15ln + -15ln = 0
-13ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-13 + 2x) = 0
