Solution for ln(7x-2)+ln(x-1)=lnx equation:


Simplifying
ln(7x + -2) + ln(x + -1) = lnx

Reorder the terms:
ln(-2 + 7x) + ln(x + -1) = lnx
(-2 * ln + 7x * ln) + ln(x + -1) = lnx
(-2ln + 7lnx) + ln(x + -1) = lnx

Reorder the terms:
-2ln + 7lnx + ln(-1 + x) = lnx
-2ln + 7lnx + (-1 * ln + x * ln) = lnx
-2ln + 7lnx + (-1ln + lnx) = lnx

Reorder the terms:
-2ln + -1ln + 7lnx + lnx = lnx

Combine like terms: -2ln + -1ln = -3ln
-3ln + 7lnx + lnx = lnx

Combine like terms: 7lnx + lnx = 8lnx
-3ln + 8lnx = lnx

Solving
-3ln + 8lnx = lnx

Solving for variable 'l'.

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

Add '-1lnx' to each side of the equation.
-3ln + 8lnx + -1lnx = lnx + -1lnx

Combine like terms: 8lnx + -1lnx = 7lnx
-3ln + 7lnx = lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
-3ln + 7lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-3 + 7x) = 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 '(-3 + 7x)' equal to zero and attempt to solve: Simplifying -3 + 7x = 0 Solving -3 + 7x = 0 Move all terms containing l to the left, all other terms to the right. Add '3' to each side of the equation. -3 + 3 + 7x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 7x = 0 + 3 7x = 0 + 3 Combine like terms: 0 + 3 = 3 7x = 3 Add '-7x' to each side of the equation. 7x + -7x = 3 + -7x Combine like terms: 7x + -7x = 0 0 = 3 + -7x Simplifying 0 = 3 + -7x 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.
