Solution for ln(x)+ln(x-7)=ln(6x) equation:


Simplifying
ln(x) + ln(x + -7) = ln(6x)

Multiply ln * x
lnx + ln(x + -7) = ln(6x)

Reorder the terms:
lnx + ln(-7 + x) = ln(6x)
lnx + (-7 * ln + x * ln) = ln(6x)
lnx + (-7ln + lnx) = ln(6x)

Reorder the terms:
-7ln + lnx + lnx = ln(6x)

Combine like terms: lnx + lnx = 2lnx
-7ln + 2lnx = ln(6x)

Remove parenthesis around (6x)
-7ln + 2lnx = ln * 6x

Reorder the terms for easier multiplication:
-7ln + 2lnx = 6ln * x

Multiply ln * x
-7ln + 2lnx = 6lnx

Solving
-7ln + 2lnx = 6lnx

Solving for variable 'l'.

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

Add '-6lnx' to each side of the equation.
-7ln + 2lnx + -6lnx = 6lnx + -6lnx

Combine like terms: 2lnx + -6lnx = -4lnx
-7ln + -4lnx = 6lnx + -6lnx

Combine like terms: 6lnx + -6lnx = 0
-7ln + -4lnx = 0

Factor out the Greatest Common Factor (GCF), '-1ln'.
-1ln(7 + 4x) = 0

Ignore the factor -1.

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 '(7 + 4x)' equal to zero and attempt to solve: Simplifying 7 + 4x = 0 Solving 7 + 4x = 0 Move all terms containing l to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 4x = 0 + -7 Combine like terms: 7 + -7 = 0 0 + 4x = 0 + -7 4x = 0 + -7 Combine like terms: 0 + -7 = -7 4x = -7 Add '-4x' to each side of the equation. 4x + -4x = -7 + -4x Combine like terms: 4x + -4x = 0 0 = -7 + -4x Simplifying 0 = -7 + -4x 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.
