Solution for ln(x+5)-ln(x-3)=ln(x) equation:


Simplifying
ln(x + 5) + -1ln(x + -3) = ln(x)

Reorder the terms:
ln(5 + x) + -1ln(x + -3) = ln(x)
(5 * ln + x * ln) + -1ln(x + -3) = ln(x)
(5ln + lnx) + -1ln(x + -3) = ln(x)

Reorder the terms:
5ln + lnx + -1ln(-3 + x) = ln(x)
5ln + lnx + (-3 * -1ln + x * -1ln) = ln(x)
5ln + lnx + (3ln + -1lnx) = ln(x)

Reorder the terms:
5ln + 3ln + lnx + -1lnx = ln(x)

Combine like terms: 5ln + 3ln = 8ln
8ln + lnx + -1lnx = ln(x)

Combine like terms: lnx + -1lnx = 0
8ln + 0 = ln(x)
8ln = ln(x)

Multiply ln * x
8ln = lnx

Solving
8ln = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
8ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
8ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(8 + -1x) = 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

Set the factor '(8 + -1x)' equal to zero and attempt to solve: Simplifying 8 + -1x = 0 Solving 8 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-8' to each side of the equation. 8 + -8 + -1x = 0 + -8 Combine like terms: 8 + -8 = 0 0 + -1x = 0 + -8 -1x = 0 + -8 Combine like terms: 0 + -8 = -8 -1x = -8 Add 'x' to each side of the equation. -1x + x = -8 + x Combine like terms: -1x + x = 0 0 = -8 + x Simplifying 0 = -8 + x The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
