Solution for ln(2t+7)=ln(3)-ln(t+1) equation:


Simplifying
ln(2t + 7) = ln(3) + -1ln(t + 1)

Reorder the terms:
ln(7 + 2t) = ln(3) + -1ln(t + 1)
(7 * ln + 2t * ln) = ln(3) + -1ln(t + 1)
(7ln + 2lnt) = ln(3) + -1ln(t + 1)

Reorder the terms for easier multiplication:
7ln + 2lnt = 3ln + -1ln(t + 1)

Reorder the terms:
7ln + 2lnt = 3ln + -1ln(1 + t)
7ln + 2lnt = 3ln + (1 * -1ln + t * -1ln)
7ln + 2lnt = 3ln + (-1ln + -1lnt)

Combine like terms: 3ln + -1ln = 2ln
7ln + 2lnt = 2ln + -1lnt

Solving
7ln + 2lnt = 2ln + -1lnt

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.
7ln + -2ln + 2lnt = 2ln + -2ln + -1lnt

Combine like terms: 7ln + -2ln = 5ln
5ln + 2lnt = 2ln + -2ln + -1lnt

Combine like terms: 2ln + -2ln = 0
5ln + 2lnt = 0 + -1lnt
5ln + 2lnt = -1lnt

Add 'lnt' to each side of the equation.
5ln + 2lnt + lnt = -1lnt + lnt

Combine like terms: 2lnt + lnt = 3lnt
5ln + 3lnt = -1lnt + lnt

Combine like terms: -1lnt + lnt = 0
5ln + 3lnt = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(5 + 3t) = 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 + 3t)' equal to zero and attempt to solve: Simplifying 5 + 3t = 0 Solving 5 + 3t = 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 + 3t = 0 + -5 Combine like terms: 5 + -5 = 0 0 + 3t = 0 + -5 3t = 0 + -5 Combine like terms: 0 + -5 = -5 3t = -5 Add '-3t' to each side of the equation. 3t + -3t = -5 + -3t Combine like terms: 3t + -3t = 0 0 = -5 + -3t Simplifying 0 = -5 + -3t 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.
