Solution for 2ln(x)=ln(4)+ln(x+15) equation:


Simplifying
2ln(x) = ln(4) + ln(x + 15)

Multiply ln * x
2lnx = ln(4) + ln(x + 15)

Reorder the terms for easier multiplication:
2lnx = 4ln + ln(x + 15)

Reorder the terms:
2lnx = 4ln + ln(15 + x)
2lnx = 4ln + (15 * ln + x * ln)
2lnx = 4ln + (15ln + lnx)

Combine like terms: 4ln + 15ln = 19ln
2lnx = 19ln + lnx

Solving
2lnx = 19ln + lnx

Solving for variable 'l'.

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

Add '-19ln' to each side of the equation.
-19ln + 2lnx = 19ln + -19ln + lnx

Combine like terms: 19ln + -19ln = 0
-19ln + 2lnx = 0 + lnx
-19ln + 2lnx = lnx

Add '-1lnx' to each side of the equation.
-19ln + 2lnx + -1lnx = lnx + -1lnx

Combine like terms: 2lnx + -1lnx = 1lnx
-19ln + 1lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-19ln + 1lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-19 + x) = 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 '(-19 + x)' equal to zero and attempt to solve: Simplifying -19 + x = 0 Solving -19 + x = 0 Move all terms containing l to the left, all other terms to the right. Add '19' to each side of the equation. -19 + 19 + x = 0 + 19 Combine like terms: -19 + 19 = 0 0 + x = 0 + 19 x = 0 + 19 Combine like terms: 0 + 19 = 19 x = 19 Add '-1x' to each side of the equation. x + -1x = 19 + -1x Combine like terms: x + -1x = 0 0 = 19 + -1x Simplifying 0 = 19 + -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.
