Solution for ln(x+9)+ln(x-4)=2lnx equation:


Simplifying
ln(x + 9) + ln(x + -4) = 2lnx

Reorder the terms:
ln(9 + x) + ln(x + -4) = 2lnx
(9 * ln + x * ln) + ln(x + -4) = 2lnx
(9ln + lnx) + ln(x + -4) = 2lnx

Reorder the terms:
9ln + lnx + ln(-4 + x) = 2lnx
9ln + lnx + (-4 * ln + x * ln) = 2lnx
9ln + lnx + (-4ln + lnx) = 2lnx

Reorder the terms:
9ln + -4ln + lnx + lnx = 2lnx

Combine like terms: 9ln + -4ln = 5ln
5ln + lnx + lnx = 2lnx

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

Add '-2lnx' to each side of the equation.
5ln + 2lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
5ln + 0 = 2lnx + -2lnx
5ln = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
5ln = 0

Solving
5ln = 0

Solving for variable 'l'.

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