Solution for ln(x+8)=ln(x+3)+ln(x) equation:


Simplifying
ln(x + 8) = ln(x + 3) + ln(x)

Reorder the terms:
ln(8 + x) = ln(x + 3) + ln(x)
(8 * ln + x * ln) = ln(x + 3) + ln(x)
(8ln + lnx) = ln(x + 3) + ln(x)

Reorder the terms:
8ln + lnx = ln(3 + x) + ln(x)
8ln + lnx = (3 * ln + x * ln) + ln(x)
8ln + lnx = (3ln + lnx) + ln(x)

Multiply ln * x
8ln + lnx = 3ln + lnx + lnx

Combine like terms: lnx + lnx = 2lnx
8ln + lnx = 3ln + 2lnx

Solving
8ln + lnx = 3ln + 2lnx

Solving for variable 'l'.

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

Add '-3ln' to each side of the equation.
8ln + -3ln + lnx = 3ln + -3ln + 2lnx

Combine like terms: 8ln + -3ln = 5ln
5ln + lnx = 3ln + -3ln + 2lnx

Combine like terms: 3ln + -3ln = 0
5ln + lnx = 0 + 2lnx
5ln + lnx = 2lnx

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

Combine like terms: lnx + -2lnx = -1lnx
5ln + -1lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
5ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(5 + -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 '(5 + -1x)' equal to zero and attempt to solve: Simplifying 5 + -1x = 0 Solving 5 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-5' to each side of the equation. 5 + -5 + -1x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + -1x = 0 + -5 -1x = 0 + -5 Combine like terms: 0 + -5 = -5 -1x = -5 Add 'x' to each side of the equation. -1x + x = -5 + x Combine like terms: -1x + x = 0 0 = -5 + x Simplifying 0 = -5 + 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.
