Solution for ln*15=ln*(x-1)-ln*12 equation:


Simplifying
ln * 15 = ln(x + -1) + -1ln * 12

Reorder the terms for easier multiplication:
15ln = ln(x + -1) + -1ln * 12

Reorder the terms:
15ln = ln(-1 + x) + -1ln * 12
15ln = (-1 * ln + x * ln) + -1ln * 12
15ln = (-1ln + lnx) + -1ln * 12

Reorder the terms for easier multiplication:
15ln = -1ln + lnx + -1 * 12ln

Multiply -1 * 12
15ln = -1ln + lnx + -12ln

Reorder the terms:
15ln = -1ln + -12ln + lnx

Combine like terms: -1ln + -12ln = -13ln
15ln = -13ln + lnx

Solving
15ln = -13ln + lnx

Solving for variable 'l'.

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

Add '13ln' to each side of the equation.
15ln + 13ln = -13ln + 13ln + lnx

Combine like terms: 15ln + 13ln = 28ln
28ln = -13ln + 13ln + lnx

Combine like terms: -13ln + 13ln = 0
28ln = 0 + lnx
28ln = lnx

Add '-1lnx' to each side of the equation.
28ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
28ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(28 + -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 '(28 + -1x)' equal to zero and attempt to solve: Simplifying 28 + -1x = 0 Solving 28 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-28' to each side of the equation. 28 + -28 + -1x = 0 + -28 Combine like terms: 28 + -28 = 0 0 + -1x = 0 + -28 -1x = 0 + -28 Combine like terms: 0 + -28 = -28 -1x = -28 Add 'x' to each side of the equation. -1x + x = -28 + x Combine like terms: -1x + x = 0 0 = -28 + x Simplifying 0 = -28 + 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.
