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


Simplifying
ln(3x + 3) = ln(2x + -2)

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

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

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

Solving for variable 'l'.

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

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

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

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

Add '-2lnx' to each side of the equation.
5ln + 3lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 3lnx + -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 + 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 '(5 + x)' equal to zero and attempt to solve: Simplifying 5 + x = 0 Solving 5 + x = 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 + x = 0 + -5 Combine like terms: 5 + -5 = 0 0 + x = 0 + -5 x = 0 + -5 Combine like terms: 0 + -5 = -5 x = -5 Add '-1x' to each side of the equation. x + -1x = -5 + -1x Combine like terms: x + -1x = 0 0 = -5 + -1x Simplifying 0 = -5 + -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.
