Solution for ln(7x+10)-ln(x)=ln(8) equation:


Simplifying
ln(7x + 10) + -1ln(x) = ln(8)

Reorder the terms:
ln(10 + 7x) + -1ln(x) = ln(8)
(10 * ln + 7x * ln) + -1ln(x) = ln(8)
(10ln + 7lnx) + -1ln(x) = ln(8)

Multiply ln * x
10ln + 7lnx + -1lnx = ln(8)

Combine like terms: 7lnx + -1lnx = 6lnx
10ln + 6lnx = ln(8)

Reorder the terms for easier multiplication:
10ln + 6lnx = 8ln

Solving
10ln + 6lnx = 8ln

Solving for variable 'l'.

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

Add '-8ln' to each side of the equation.
10ln + -8ln + 6lnx = 8ln + -8ln

Combine like terms: 10ln + -8ln = 2ln
2ln + 6lnx = 8ln + -8ln

Combine like terms: 8ln + -8ln = 0
2ln + 6lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(1 + 3x) = 0

Ignore the factor 2.

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 + 3x)' equal to zero and attempt to solve: Simplifying 1 + 3x = 0 Solving 1 + 3x = 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 + 3x = 0 + -1 Combine like terms: 1 + -1 = 0 0 + 3x = 0 + -1 3x = 0 + -1 Combine like terms: 0 + -1 = -1 3x = -1 Add '-3x' to each side of the equation. 3x + -3x = -1 + -3x Combine like terms: 3x + -3x = 0 0 = -1 + -3x Simplifying 0 = -1 + -3x 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.
