Solution for Ln(x+7)=2ln(3)-ln(x-7) equation:


Simplifying
Ln(x + 7) = 2ln(3) + -1ln(x + -7)

Reorder the terms:
nL(7 + x) = 2ln(3) + -1ln(x + -7)
(7 * nL + x * nL) = 2ln(3) + -1ln(x + -7)
(7nL + nxL) = 2ln(3) + -1ln(x + -7)

Reorder the terms for easier multiplication:
7nL + nxL = 2 * 3ln + -1ln(x + -7)

Multiply 2 * 3
7nL + nxL = 6ln + -1ln(x + -7)

Reorder the terms:
7nL + nxL = 6ln + -1ln(-7 + x)
7nL + nxL = 6ln + (-7 * -1ln + x * -1ln)
7nL + nxL = 6ln + (7ln + -1lnx)

Combine like terms: 6ln + 7ln = 13ln
7nL + nxL = 13ln + -1lnx

Solving
7nL + nxL = 13ln + -1lnx

Solving for variable 'n'.

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

Add '-13ln' to each side of the equation.
7nL + -13ln + nxL = 13ln + -13ln + -1lnx

Reorder the terms:
-13ln + 7nL + nxL = 13ln + -13ln + -1lnx

Combine like terms: 13ln + -13ln = 0
-13ln + 7nL + nxL = 0 + -1lnx
-13ln + 7nL + nxL = -1lnx

Add 'lnx' to each side of the equation.
-13ln + 7nL + lnx + nxL = -1lnx + lnx

Reorder the terms:
-13ln + lnx + 7nL + nxL = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-13ln + lnx + 7nL + nxL = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(-13l + lx + 7L + xL) = 0

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing n to the left, all other terms to the right. Simplifying n = 0

Subproblem 2

Set the factor '(-13l + lx + 7L + xL)' equal to zero and attempt to solve: Simplifying -13l + lx + 7L + xL = 0 Reorder the terms: 7L + -13l + lx + xL = 0 Solving 7L + -13l + lx + xL = 0 Move all terms containing n to the left, all other terms to the right. Add '-7L' to each side of the equation. 7L + -13l + lx + -7L + xL = 0 + -7L Reorder the terms: 7L + -7L + -13l + lx + xL = 0 + -7L Combine like terms: 7L + -7L = 0 0 + -13l + lx + xL = 0 + -7L -13l + lx + xL = 0 + -7L Remove the zero: -13l + lx + xL = -7L Add '13l' to each side of the equation. -13l + lx + 13l + xL = -7L + 13l Reorder the terms: -13l + 13l + lx + xL = -7L + 13l Combine like terms: -13l + 13l = 0 0 + lx + xL = -7L + 13l lx + xL = -7L + 13l Add '-1lx' to each side of the equation. lx + -1lx + xL = -7L + 13l + -1lx Combine like terms: lx + -1lx = 0 0 + xL = -7L + 13l + -1lx xL = -7L + 13l + -1lx Add '-1xL' to each side of the equation. xL + -1xL = -7L + 13l + -1lx + -1xL Combine like terms: xL + -1xL = 0 0 = -7L + 13l + -1lx + -1xL Simplifying 0 = -7L + 13l + -1lx + -1xL The solution to this equation could not be determined.
