Solution for ln(z+1)-ln(z-1)=lnx equation:


Simplifying
ln(z + 1) + -1ln(z + -1) = lnx

Reorder the terms:
ln(1 + z) + -1ln(z + -1) = lnx
(1 * ln + z * ln) + -1ln(z + -1) = lnx
(1ln + lnz) + -1ln(z + -1) = lnx

Reorder the terms:
1ln + lnz + -1ln(-1 + z) = lnx
1ln + lnz + (-1 * -1ln + z * -1ln) = lnx
1ln + lnz + (1ln + -1lnz) = lnx

Reorder the terms:
1ln + 1ln + lnz + -1lnz = lnx

Combine like terms: 1ln + 1ln = 2ln
2ln + lnz + -1lnz = lnx

Combine like terms: lnz + -1lnz = 0
2ln + 0 = lnx
2ln = lnx

Solving
2ln = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
2ln + -1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
2ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(2 + -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 '(2 + -1x)' equal to zero and attempt to solve: Simplifying 2 + -1x = 0 Solving 2 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + -2 + -1x = 0 + -2 Combine like terms: 2 + -2 = 0 0 + -1x = 0 + -2 -1x = 0 + -2 Combine like terms: 0 + -2 = -2 -1x = -2 Add 'x' to each side of the equation. -1x + x = -2 + x Combine like terms: -1x + x = 0 0 = -2 + x Simplifying 0 = -2 + 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.
