Solution for ln(r+4)=ln(5s+2) equation:


Simplifying
ln(r + 4) = ln(5s + 2)

Reorder the terms:
ln(4 + r) = ln(5s + 2)
(4 * ln + r * ln) = ln(5s + 2)
(4ln + lnr) = ln(5s + 2)

Reorder the terms:
4ln + lnr = ln(2 + 5s)
4ln + lnr = (2 * ln + 5s * ln)
4ln + lnr = (2ln + 5lns)

Solving
4ln + lnr = 2ln + 5lns

Solving for variable 'l'.

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

Add '-2ln' to each side of the equation.
4ln + -2ln + lnr = 2ln + -2ln + 5lns

Combine like terms: 4ln + -2ln = 2ln
2ln + lnr = 2ln + -2ln + 5lns

Combine like terms: 2ln + -2ln = 0
2ln + lnr = 0 + 5lns
2ln + lnr = 5lns

Add '-5lns' to each side of the equation.
2ln + lnr + -5lns = 5lns + -5lns

Combine like terms: 5lns + -5lns = 0
2ln + lnr + -5lns = 0

Factor out the Greatest Common Factor (GCF), 'ln'.
ln(2 + r + -5s) = 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 '(2 + r + -5s)' equal to zero and attempt to solve: Simplifying 2 + r + -5s = 0 Solving 2 + r + -5s = 0 Move all terms containing l to the left, all other terms to the right. Add '-2' to each side of the equation. 2 + r + -2 + -5s = 0 + -2 Reorder the terms: 2 + -2 + r + -5s = 0 + -2 Combine like terms: 2 + -2 = 0 0 + r + -5s = 0 + -2 r + -5s = 0 + -2 Combine like terms: 0 + -2 = -2 r + -5s = -2 Add '-1r' to each side of the equation. r + -1r + -5s = -2 + -1r Combine like terms: r + -1r = 0 0 + -5s = -2 + -1r -5s = -2 + -1r Add '5s' to each side of the equation. -5s + 5s = -2 + -1r + 5s Combine like terms: -5s + 5s = 0 0 = -2 + -1r + 5s Simplifying 0 = -2 + -1r + 5s 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.
