Solution for ln(x+3)+ln(x)=ln(11x-15) equation:


Simplifying
ln(x + 3) + ln(x) = ln(11x + -15)

Reorder the terms:
ln(3 + x) + ln(x) = ln(11x + -15)
(3 * ln + x * ln) + ln(x) = ln(11x + -15)
(3ln + lnx) + ln(x) = ln(11x + -15)

Multiply ln * x
3ln + lnx + lnx = ln(11x + -15)

Combine like terms: lnx + lnx = 2lnx
3ln + 2lnx = ln(11x + -15)

Reorder the terms:
3ln + 2lnx = ln(-15 + 11x)
3ln + 2lnx = (-15 * ln + 11x * ln)
3ln + 2lnx = (-15ln + 11lnx)

Solving
3ln + 2lnx = -15ln + 11lnx

Solving for variable 'l'.

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

Add '15ln' to each side of the equation.
3ln + 15ln + 2lnx = -15ln + 15ln + 11lnx

Combine like terms: 3ln + 15ln = 18ln
18ln + 2lnx = -15ln + 15ln + 11lnx

Combine like terms: -15ln + 15ln = 0
18ln + 2lnx = 0 + 11lnx
18ln + 2lnx = 11lnx

Add '-11lnx' to each side of the equation.
18ln + 2lnx + -11lnx = 11lnx + -11lnx

Combine like terms: 2lnx + -11lnx = -9lnx
18ln + -9lnx = 11lnx + -11lnx

Combine like terms: 11lnx + -11lnx = 0
18ln + -9lnx = 0

Factor out the Greatest Common Factor (GCF), '9ln'.
9ln(2 + -1x) = 0

Ignore the factor 9.

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