4ln + 2lnx = 45ln

Solving
4ln + 2lnx = 45ln

Solving for variable 'l'.

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

Add '-45ln' to each side of the equation.
4ln + -45ln + 2lnx = 45ln + -45ln

Combine like terms: 4ln + -45ln = -41ln
-41ln + 2lnx = 45ln + -45ln

Combine like terms: 45ln + -45ln = 0
-41ln + 2lnx = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(-41 + 2x) = 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 '(-41 + 2x)' equal to zero and attempt to solve: Simplifying -41 + 2x = 0 Solving -41 + 2x = 0 Move all terms containing l to the left, all other terms to the right. Add '41' to each side of the equation. -41 + 41 + 2x = 0 + 41 Combine like terms: -41 + 41 = 0 0 + 2x = 0 + 41 2x = 0 + 41 Combine like terms: 0 + 41 = 41 2x = 41 Add '-2x' to each side of the equation. 2x + -2x = 41 + -2x Combine like terms: 2x + -2x = 0 0 = 41 + -2x Simplifying 0 = 41 + -2x 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.
