Solution for ln(5x+3)=ln(2x) equation:


Simplifying
ln(5x + 3) = ln(2x)

Reorder the terms:
ln(3 + 5x) = ln(2x)
(3 * ln + 5x * ln) = ln(2x)
(3ln + 5lnx) = ln(2x)

Remove parenthesis around (2x)
3ln + 5lnx = ln * 2x

Reorder the terms for easier multiplication:
3ln + 5lnx = 2ln * x

Multiply ln * x
3ln + 5lnx = 2lnx

Solving
3ln + 5lnx = 2lnx

Solving for variable 'l'.

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

Add '-2lnx' to each side of the equation.
3ln + 5lnx + -2lnx = 2lnx + -2lnx

Combine like terms: 5lnx + -2lnx = 3lnx
3ln + 3lnx = 2lnx + -2lnx

Combine like terms: 2lnx + -2lnx = 0
3ln + 3lnx = 0

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

Ignore the factor 3.

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