Solution for ln(3x-8)+ln(x-4)=2lnx equation:


Simplifying
ln(3x + -8) + ln(x + -4) = 2lnx

Reorder the terms:
ln(-8 + 3x) + ln(x + -4) = 2lnx
(-8 * ln + 3x * ln) + ln(x + -4) = 2lnx
(-8ln + 3lnx) + ln(x + -4) = 2lnx

Reorder the terms:
-8ln + 3lnx + ln(-4 + x) = 2lnx
-8ln + 3lnx + (-4 * ln + x * ln) = 2lnx
-8ln + 3lnx + (-4ln + lnx) = 2lnx

Reorder the terms:
-8ln + -4ln + 3lnx + lnx = 2lnx

Combine like terms: -8ln + -4ln = -12ln
-12ln + 3lnx + lnx = 2lnx

Combine like terms: 3lnx + lnx = 4lnx
-12ln + 4lnx = 2lnx

Solving
-12ln + 4lnx = 2lnx

Solving for variable 'l'.

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

Add '-2lnx' to each side of the equation.
-12ln + 4lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 4lnx + -2lnx = 2lnx
-12ln + 2lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
-12ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-6 + x) = 0

Ignore the factor 2.

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 '(-6 + x)' equal to zero and attempt to solve: Simplifying -6 + x = 0 Solving -6 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '6' to each side of the equation. -6 + 6 + x = 0 + 6 Combine like terms: -6 + 6 = 0 0 + x = 0 + 6 x = 0 + 6 Combine like terms: 0 + 6 = 6 x = 6 Add '-1x' to each side of the equation. x + -1x = 6 + -1x Combine like terms: x + -1x = 0 0 = 6 + -1x Simplifying 0 = 6 + -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.
