Solution for ln(x+4)+ln(x-9)=ln(14) equation: 


Simplifying
ln(x + 4) + ln(x + -9) = ln(14)

Reorder the terms:
ln(4 + x) + ln(x + -9) = ln(14)
(4 * ln + x * ln) + ln(x + -9) = ln(14)
(4ln + lnx) + ln(x + -9) = ln(14)

Reorder the terms:
4ln + lnx + ln(-9 + x) = ln(14)
4ln + lnx + (-9 * ln + x * ln) = ln(14)
4ln + lnx + (-9ln + lnx) = ln(14)

Reorder the terms:
4ln + -9ln + lnx + lnx = ln(14)

Combine like terms: 4ln + -9ln = -5ln
-5ln + lnx + lnx = ln(14)

Combine like terms: lnx + lnx = 2lnx
-5ln + 2lnx = ln(14)

Reorder the terms for easier multiplication:
-5ln + 2lnx = 14ln

Solving
-5ln + 2lnx = 14ln

Solving for variable 'l'.

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

Add '-14ln' to each side of the equation.
-5ln + -14ln + 2lnx = 14ln + -14ln

Combine like terms: -5ln + -14ln = -19ln
-19ln + 2lnx = 14ln + -14ln

Combine like terms: 14ln + -14ln = 0
-19ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-19 + 2x) = 0


Subproblem 1
Set the factor 'ln' equal to zero and attempt to solve:
