Solution for ln(x-9)-2*ln(x-3)=-2*ln(5) equation:


Simplifying
ln(x + -9) + -2ln(x + -3) = -2ln(5)

Reorder the terms:
ln(-9 + x) + -2ln(x + -3) = -2ln(5)
(-9 * ln + x * ln) + -2ln(x + -3) = -2ln(5)
(-9ln + lnx) + -2ln(x + -3) = -2ln(5)

Reorder the terms:
-9ln + lnx + -2ln(-3 + x) = -2ln(5)
-9ln + lnx + (-3 * -2ln + x * -2ln) = -2ln(5)
-9ln + lnx + (6ln + -2lnx) = -2ln(5)

Reorder the terms:
-9ln + 6ln + lnx + -2lnx = -2ln(5)

Combine like terms: -9ln + 6ln = -3ln
-3ln + lnx + -2lnx = -2ln(5)

Combine like terms: lnx + -2lnx = -1lnx
-3ln + -1lnx = -2ln(5)

Reorder the terms for easier multiplication:
-3ln + -1lnx = -2 * 5ln

Multiply -2 * 5
-3ln + -1lnx = -10ln

Solving
-3ln + -1lnx = -10ln

Solving for variable 'l'.

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

Add '10ln' to each side of the equation.
-3ln + 10ln + -1lnx = -10ln + 10ln

Combine like terms: -3ln + 10ln = 7ln
7ln + -1lnx = -10ln + 10ln

Combine like terms: -10ln + 10ln = 0
7ln + -1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(7 + -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 '(7 + -1x)' equal to zero and attempt to solve: Simplifying 7 + -1x = 0 Solving 7 + -1x = 0 Move all terms containing l to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + -1x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + -1x = 0 + -7 -1x = 0 + -7 Combine like terms: 0 + -7 = -7 -1x = -7 Add 'x' to each side of the equation. -1x + x = -7 + x Combine like terms: -1x + x = 0 0 = -7 + x Simplifying 0 = -7 + 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.
