Solution for ln(x+7)+ln(x-5)=2lnx equation:


Simplifying
ln(x + 7) + ln(x + -5) = 2lnx

Reorder the terms:
ln(7 + x) + ln(x + -5) = 2lnx
(7 * ln + x * ln) + ln(x + -5) = 2lnx
(7ln + lnx) + ln(x + -5) = 2lnx

Reorder the terms:
7ln + lnx + ln(-5 + x) = 2lnx
7ln + lnx + (-5 * ln + x * ln) = 2lnx
7ln + lnx + (-5ln + lnx) = 2lnx

Reorder the terms:
7ln + -5ln + lnx + lnx = 2lnx

Combine like terms: 7ln + -5ln = 2ln
2ln + lnx + lnx = 2lnx

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

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

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

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

Solving
2ln = 0

Solving for variable 'l'.

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