Solution for ln(9x+4)-ln(x)=ln(10) equation:


Simplifying
ln(9x + 4) + -1ln(x) = ln(10)

Reorder the terms:
ln(4 + 9x) + -1ln(x) = ln(10)
(4 * ln + 9x * ln) + -1ln(x) = ln(10)
(4ln + 9lnx) + -1ln(x) = ln(10)

Multiply ln * x
4ln + 9lnx + -1lnx = ln(10)

Combine like terms: 9lnx + -1lnx = 8lnx
4ln + 8lnx = ln(10)

Reorder the terms for easier multiplication:
4ln + 8lnx = 10ln

Solving
4ln + 8lnx = 10ln

Solving for variable 'l'.

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

Add '-10ln' to each side of the equation.
4ln + -10ln + 8lnx = 10ln + -10ln

Combine like terms: 4ln + -10ln = -6ln
-6ln + 8lnx = 10ln + -10ln

Combine like terms: 10ln + -10ln = 0
-6ln + 8lnx = 0

Factor out the Greatest Common Factor (GCF), '2ln'.
2ln(-3 + 4x) = 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 '(-3 + 4x)' equal to zero and attempt to solve: Simplifying -3 + 4x = 0 Solving -3 + 4x = 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 + 4x = 0 + 3 Combine like terms: -3 + 3 = 0 0 + 4x = 0 + 3 4x = 0 + 3 Combine like terms: 0 + 3 = 3 4x = 3 Add '-4x' to each side of the equation. 4x + -4x = 3 + -4x Combine like terms: 4x + -4x = 0 0 = 3 + -4x Simplifying 0 = 3 + -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.
