Solution for ln(x)+ln(x-4)=ln(30-3x) equation:


Simplifying
ln(x) + ln(x + -4) = ln(30 + -3x)

Multiply ln * x
lnx + ln(x + -4) = ln(30 + -3x)

Reorder the terms:
lnx + ln(-4 + x) = ln(30 + -3x)
lnx + (-4 * ln + x * ln) = ln(30 + -3x)
lnx + (-4ln + lnx) = ln(30 + -3x)

Reorder the terms:
-4ln + lnx + lnx = ln(30 + -3x)

Combine like terms: lnx + lnx = 2lnx
-4ln + 2lnx = ln(30 + -3x)
-4ln + 2lnx = (30 * ln + -3x * ln)
-4ln + 2lnx = (30ln + -3lnx)

Solving
-4ln + 2lnx = 30ln + -3lnx

Solving for variable 'l'.

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

Add '-30ln' to each side of the equation.
-4ln + -30ln + 2lnx = 30ln + -30ln + -3lnx

Combine like terms: -4ln + -30ln = -34ln
-34ln + 2lnx = 30ln + -30ln + -3lnx

Combine like terms: 30ln + -30ln = 0
-34ln + 2lnx = 0 + -3lnx
-34ln + 2lnx = -3lnx

Add '3lnx' to each side of the equation.
-34ln + 2lnx + 3lnx = -3lnx + 3lnx

Combine like terms: 2lnx + 3lnx = 5lnx
-34ln + 5lnx = -3lnx + 3lnx

Combine like terms: -3lnx + 3lnx = 0
-34ln + 5lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-34 + 5x) = 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 '(-34 + 5x)' equal to zero and attempt to solve: Simplifying -34 + 5x = 0 Solving -34 + 5x = 0 Move all terms containing l to the left, all other terms to the right. Add '34' to each side of the equation. -34 + 34 + 5x = 0 + 34 Combine like terms: -34 + 34 = 0 0 + 5x = 0 + 34 5x = 0 + 34 Combine like terms: 0 + 34 = 34 5x = 34 Add '-5x' to each side of the equation. 5x + -5x = 34 + -5x Combine like terms: 5x + -5x = 0 0 = 34 + -5x Simplifying 0 = 34 + -5x 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.
