Solution for ln*20=ln*4+ln*(x-7) equation:


Simplifying
ln * 20 = ln * 4 + ln(x + -7)

Reorder the terms for easier multiplication:
20ln = ln * 4 + ln(x + -7)

Reorder the terms for easier multiplication:
20ln = 4ln + ln(x + -7)

Reorder the terms:
20ln = 4ln + ln(-7 + x)
20ln = 4ln + (-7 * ln + x * ln)
20ln = 4ln + (-7ln + lnx)

Combine like terms: 4ln + -7ln = -3ln
20ln = -3ln + lnx

Solving
20ln = -3ln + lnx

Solving for variable 'l'.

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

Add '3ln' to each side of the equation.
20ln + 3ln = -3ln + 3ln + lnx

Combine like terms: 20ln + 3ln = 23ln
23ln = -3ln + 3ln + lnx

Combine like terms: -3ln + 3ln = 0
23ln = 0 + lnx
23ln = lnx

Add '-1lnx' to each side of the equation.
23ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
23ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(23 + -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 '(23 + -1x)' equal to zero and attempt to solve: Simplifying 23 + -1x = 0 Solving 23 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-23' to each side of the equation. 23 + -23 + -1x = 0 + -23 Combine like terms: 23 + -23 = 0 0 + -1x = 0 + -23 -1x = 0 + -23 Combine like terms: 0 + -23 = -23 -1x = -23 Add 'x' to each side of the equation. -1x + x = -23 + x Combine like terms: -1x + x = 0 0 = -23 + x Simplifying 0 = -23 + 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.
