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


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

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

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

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

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

Reorder the terms for easier multiplication:
3ln + 2lnx = 4ln

Solving
3ln + 2lnx = 4ln

Solving for variable 'l'.

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

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

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

Combine like terms: 4ln + -4ln = 0
-1ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-1 + 2x) = 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 '(-1 + 2x)' equal to zero and attempt to solve: Simplifying -1 + 2x = 0 Solving -1 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '1' to each side of the equation. -1 + 1 + 2x = 0 + 1 Combine like terms: -1 + 1 = 0 0 + 2x = 0 + 1 2x = 0 + 1 Combine like terms: 0 + 1 = 1 2x = 1 Add '-2x' to each side of the equation. 2x + -2x = 1 + -2x Combine like terms: 2x + -2x = 0 0 = 1 + -2x Simplifying 0 = 1 + -2x 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.
