Solution for ln(5x+3)=ln(7)-ln(x-2) equation:


Simplifying
ln(5x + 3) = ln(7) + -1ln(x + -2)

Reorder the terms:
ln(3 + 5x) = ln(7) + -1ln(x + -2)
(3 * ln + 5x * ln) = ln(7) + -1ln(x + -2)
(3ln + 5lnx) = ln(7) + -1ln(x + -2)

Reorder the terms for easier multiplication:
3ln + 5lnx = 7ln + -1ln(x + -2)

Reorder the terms:
3ln + 5lnx = 7ln + -1ln(-2 + x)
3ln + 5lnx = 7ln + (-2 * -1ln + x * -1ln)
3ln + 5lnx = 7ln + (2ln + -1lnx)

Combine like terms: 7ln + 2ln = 9ln
3ln + 5lnx = 9ln + -1lnx

Solving
3ln + 5lnx = 9ln + -1lnx

Solving for variable 'l'.

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

Add '-9ln' to each side of the equation.
3ln + -9ln + 5lnx = 9ln + -9ln + -1lnx

Combine like terms: 3ln + -9ln = -6ln
-6ln + 5lnx = 9ln + -9ln + -1lnx

Combine like terms: 9ln + -9ln = 0
-6ln + 5lnx = 0 + -1lnx
-6ln + 5lnx = -1lnx

Add 'lnx' to each side of the equation.
-6ln + 5lnx + lnx = -1lnx + lnx

Combine like terms: 5lnx + lnx = 6lnx
-6ln + 6lnx = -1lnx + lnx

Combine like terms: -1lnx + lnx = 0
-6ln + 6lnx = 0

Factor out the Greatest Common Factor (GCF), '6ln'.
6ln(-1 + x) = 0

Ignore the factor 6.

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