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


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

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

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

Add '-1lnx' to each side of the equation.
-7ln + lnx + -1lnx = 5ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-7ln + 0 = 5ln + lnx + -1lnx
-7ln = 5ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-7ln = 5ln + 0
-7ln = 5ln

Solving
-7ln = 5ln

Solving for variable 'l'.

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

Add '-5ln' to each side of the equation.
-7ln + -5ln = 5ln + -5ln

Combine like terms: -7ln + -5ln = -12ln
-12ln = 5ln + -5ln

Combine like terms: 5ln + -5ln = 0
-12ln = 0

Divide each side by '-12'.
ln = 0
