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


Simplifying
ln(4 + -1x) = 2ln(x)
(4 * ln + -1x * ln) = 2ln(x)
(4ln + -1lnx) = 2ln(x)

Multiply ln * x
4ln + -1lnx = 2lnx

Solving
4ln + -1lnx = 2lnx

Solving for variable 'l'.

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

Add '-2lnx' to each side of the equation.
4ln + -1lnx + -2lnx = 2lnx + -2lnx

Combine like terms: -1lnx + -2lnx = -3lnx
4ln + -3lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
4ln + -3lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(4 + -3x) = 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 '(4 + -3x)' equal to zero and attempt to solve: Simplifying 4 + -3x = 0 Solving 4 + -3x = 0 Move all terms containing l to the left, all other terms to the right. Add '-4' to each side of the equation. 4 + -4 + -3x = 0 + -4 Combine like terms: 4 + -4 = 0 0 + -3x = 0 + -4 -3x = 0 + -4 Combine like terms: 0 + -4 = -4 -3x = -4 Add '3x' to each side of the equation. -3x + 3x = -4 + 3x Combine like terms: -3x + 3x = 0 0 = -4 + 3x Simplifying 0 = -4 + 3x 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.
