Solution for ln(x+5)=ln(x)-ln(4) equation:


Simplifying
ln(x + 5) = ln(x) + -1ln(4)

Reorder the terms:
ln(5 + x) = ln(x) + -1ln(4)
(5 * ln + x * ln) = ln(x) + -1ln(4)
(5ln + lnx) = ln(x) + -1ln(4)

Multiply ln * x
5ln + lnx = lnx + -1ln(4)

Reorder the terms for easier multiplication:
5ln + lnx = lnx + -1 * 4ln

Multiply -1 * 4
5ln + lnx = lnx + -4ln

Reorder the terms:
5ln + lnx = -4ln + lnx

Add '-1lnx' to each side of the equation.
5ln + lnx + -1lnx = -4ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
5ln + 0 = -4ln + lnx + -1lnx
5ln = -4ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
5ln = -4ln + 0
5ln = -4ln

Solving
5ln = -4ln

Solving for variable 'l'.

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

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

Combine like terms: 5ln + 4ln = 9ln
9ln = -4ln + 4ln

Combine like terms: -4ln + 4ln = 0
9ln = 0

Divide each side by '9'.
ln = 0

Simplifying
ln = 0
