Solution for ln(x+4)=ln(8x-5) equation:


Simplifying
ln(x + 4) = ln(8x + -5)

Reorder the terms:
ln(4 + x) = ln(8x + -5)
(4 * ln + x * ln) = ln(8x + -5)
(4ln + lnx) = ln(8x + -5)

Reorder the terms:
4ln + lnx = ln(-5 + 8x)
4ln + lnx = (-5 * ln + 8x * ln)
4ln + lnx = (-5ln + 8lnx)

Solving
4ln + lnx = -5ln + 8lnx

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.
4ln + 5ln + lnx = -5ln + 5ln + 8lnx

Combine like terms: 4ln + 5ln = 9ln
9ln + lnx = -5ln + 5ln + 8lnx

Combine like terms: -5ln + 5ln = 0
9ln + lnx = 0 + 8lnx
9ln + lnx = 8lnx

Add '-8lnx' to each side of the equation.
9ln + lnx + -8lnx = 8lnx + -8lnx

Combine like terms: lnx + -8lnx = -7lnx
9ln + -7lnx = 8lnx + -8lnx

Combine like terms: 8lnx + -8lnx = 0
9ln + -7lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(9 + -7x) = 0

Subproblem 1

Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.

Subproblem 2
