Solution for ln(x)+ln(x-3)=ln(4x-12) equation:


Simplifying
ln(x) + ln(x + -3) = ln(4x + -12)

Multiply ln * x
lnx + ln(x + -3) = ln(4x + -12)

Reorder the terms:
lnx + ln(-3 + x) = ln(4x + -12)
lnx + (-3 * ln + x * ln) = ln(4x + -12)
lnx + (-3ln + lnx) = ln(4x + -12)

Reorder the terms:
-3ln + lnx + lnx = ln(4x + -12)

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

Reorder the terms:
-3ln + 2lnx = ln(-12 + 4x)
-3ln + 2lnx = (-12 * ln + 4x * ln)
-3ln + 2lnx = (-12ln + 4lnx)

Solving
-3ln + 2lnx = -12ln + 4lnx

Solving for variable 'l'.

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

Add '12ln' to each side of the equation.
-3ln + 12ln + 2lnx = -12ln + 12ln + 4lnx

Combine like terms: -3ln + 12ln = 9ln
9ln + 2lnx = -12ln + 12ln + 4lnx

Combine like terms: -12ln + 12ln = 0
9ln + 2lnx = 0 + 4lnx
9ln + 2lnx = 4lnx

Add '-4lnx' to each side of the equation.
9ln + 2lnx + -4lnx = 4lnx + -4lnx

Combine like terms: 2lnx + -4lnx = -2lnx
9ln + -2lnx = 4lnx + -4lnx

Combine like terms: 4lnx + -4lnx = 0
9ln + -2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(9 + -2x) = 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 '(9 + -2x)' equal to zero and attempt to solve: Simplifying 9 + -2x = 0 Solving 9 + -2x = 0 Move all terms containing l to the left, all other terms to the right. Add '-9' to each side of the equation. 9 + -9 + -2x = 0 + -9 Combine like terms: 9 + -9 = 0 0 + -2x = 0 + -9 -2x = 0 + -9 Combine like terms: 0 + -9 = -9 -2x = -9 Add '2x' to each side of the equation. -2x + 2x = -9 + 2x Combine like terms: -2x + 2x = 0 0 = -9 + 2x Simplifying 0 = -9 + 2x 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.
