Solution for ln(x-15)+ln(x+2)=ln(-10x-2) equation:


Simplifying
ln(x + -15) + ln(x + 2) = ln(-10x + -2)

Reorder the terms:
ln(-15 + x) + ln(x + 2) = ln(-10x + -2)
(-15 * ln + x * ln) + ln(x + 2) = ln(-10x + -2)
(-15ln + lnx) + ln(x + 2) = ln(-10x + -2)

Reorder the terms:
-15ln + lnx + ln(2 + x) = ln(-10x + -2)
-15ln + lnx + (2 * ln + x * ln) = ln(-10x + -2)
-15ln + lnx + (2ln + lnx) = ln(-10x + -2)

Reorder the terms:
-15ln + 2ln + lnx + lnx = ln(-10x + -2)

Combine like terms: -15ln + 2ln = -13ln
-13ln + lnx + lnx = ln(-10x + -2)

Combine like terms: lnx + lnx = 2lnx
-13ln + 2lnx = ln(-10x + -2)

Reorder the terms:
-13ln + 2lnx = ln(-2 + -10x)
-13ln + 2lnx = (-2 * ln + -10x * ln)
-13ln + 2lnx = (-2ln + -10lnx)

Solving
-13ln + 2lnx = -2ln + -10lnx

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.
-13ln + 2ln + 2lnx = -2ln + 2ln + -10lnx

Combine like terms: -13ln + 2ln = -11ln
-11ln + 2lnx = -2ln + 2ln + -10lnx

Combine like terms: -2ln + 2ln = 0
-11ln + 2lnx = 0 + -10lnx
-11ln + 2lnx = -10lnx

Add '10lnx' to each side of the equation.
-11ln + 2lnx + 10lnx = -10lnx + 10lnx

Combine like terms: 2lnx + 10lnx = 12lnx
-11ln + 12lnx = -10lnx + 10lnx

Combine like terms: -10lnx + 10lnx = 0
-11ln + 12lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-11 + 12x) = 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 '(-11 + 12x)' equal to zero and attempt to solve: Simplifying -11 + 12x = 0 Solving -11 + 12x = 0 Move all terms containing l to the left, all other terms to the right. Add '11' to each side of the equation. -11 + 11 + 12x = 0 + 11 Combine like terms: -11 + 11 = 0 0 + 12x = 0 + 11 12x = 0 + 11 Combine like terms: 0 + 11 = 11 12x = 11 Add '-12x' to each side of the equation. 12x + -12x = 11 + -12x Combine like terms: 12x + -12x = 0 0 = 11 + -12x Simplifying 0 = 11 + -12x 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.
