Solution for ln(2x-2)=ln(x+8) equation:


Simplifying
ln(2x + -2) = ln(x + 8)

Reorder the terms:
ln(-2 + 2x) = ln(x + 8)
(-2 * ln + 2x * ln) = ln(x + 8)
(-2ln + 2lnx) = ln(x + 8)

Reorder the terms:
-2ln + 2lnx = ln(8 + x)
-2ln + 2lnx = (8 * ln + x * ln)
-2ln + 2lnx = (8ln + lnx)

Solving
-2ln + 2lnx = 8ln + lnx

Solving for variable 'l'.

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

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

Combine like terms: -2ln + -8ln = -10ln
-10ln + 2lnx = 8ln + -8ln + lnx

Combine like terms: 8ln + -8ln = 0
-10ln + 2lnx = 0 + lnx
-10ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
-10ln + 2lnx + -1lnx = lnx + -1lnx

Combine like terms: 2lnx + -1lnx = 1lnx
-10ln + 1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-10ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-10 + x) = 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 '(-10 + x)' equal to zero and attempt to solve: Simplifying -10 + x = 0 Solving -10 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '10' to each side of the equation. -10 + 10 + x = 0 + 10 Combine like terms: -10 + 10 = 0 0 + x = 0 + 10 x = 0 + 10 Combine like terms: 0 + 10 = 10 x = 10 Add '-1x' to each side of the equation. x + -1x = 10 + -1x Combine like terms: x + -1x = 0 0 = 10 + -1x Simplifying 0 = 10 + -1x 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.
