Solution for 2lnx+ln(x-4)=ln(x+6) equation:


Simplifying
2lnx + ln(x + -4) = ln(x + 6)

Reorder the terms:
2lnx + ln(-4 + x) = ln(x + 6)
2lnx + (-4 * ln + x * ln) = ln(x + 6)
2lnx + (-4ln + lnx) = ln(x + 6)

Reorder the terms:
-4ln + 2lnx + lnx = ln(x + 6)

Combine like terms: 2lnx + lnx = 3lnx
-4ln + 3lnx = ln(x + 6)

Reorder the terms:
-4ln + 3lnx = ln(6 + x)
-4ln + 3lnx = (6 * ln + x * ln)
-4ln + 3lnx = (6ln + lnx)

Solving
-4ln + 3lnx = 6ln + lnx

Solving for variable 'l'.

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

Add '-6ln' to each side of the equation.
-4ln + -6ln + 3lnx = 6ln + -6ln + lnx

Combine like terms: -4ln + -6ln = -10ln
-10ln + 3lnx = 6ln + -6ln + lnx

Combine like terms: 6ln + -6ln = 0
-10ln + 3lnx = 0 + lnx
-10ln + 3lnx = lnx

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

Combine like terms: 3lnx + -1lnx = 2lnx
-10ln + 2lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-10ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-5 + x) = 0

Ignore the factor 2.

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 + x)' equal to zero and attempt to solve: Simplifying -5 + x = 0 Solving -5 + x = 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 + x = 0 + 5 Combine like terms: -5 + 5 = 0 0 + x = 0 + 5 x = 0 + 5 Combine like terms: 0 + 5 = 5 x = 5 Add '-1x' to each side of the equation. x + -1x = 5 + -1x Combine like terms: x + -1x = 0 0 = 5 + -1x Simplifying 0 = 5 + -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.
