Solution for ln(2x-3)=ln(x+4) equation: 


Simplifying
ln(2x + -3) = ln(x + 4)

Reorder the terms:
ln(-3 + 2x) = ln(x + 4)
(-3 * ln + 2x * ln) = ln(x + 4)
(-3ln + 2lnx) = ln(x + 4)

Reorder the terms:
-3ln + 2lnx = ln(4 + x)
-3ln + 2lnx = (4 * ln + x * ln)
-3ln + 2lnx = (4ln + lnx)

Solving
-3ln + 2lnx = 4ln + lnx

Solving for variable 'l'.

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

Add '-4ln' to each side of the equation.
-3ln + -4ln + 2lnx = 4ln + -4ln + lnx

Combine like terms: -3ln + -4ln = -7ln
-7ln + 2lnx = 4ln + -4ln + lnx

Combine like terms: 4ln + -4ln = 0
-7ln + 2lnx = 0 + lnx
-7ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
-7ln + 2lnx + -1lnx = lnx + -1lnx

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

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

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-7 + x) = 0
