Solution for ln(y+2)=ln(y-7)+ln(4) equation:


Simplifying
ln(y + 2) = ln(y + -7) + ln(4)

Reorder the terms:
ln(2 + y) = ln(y + -7) + ln(4)
(2 * ln + y * ln) = ln(y + -7) + ln(4)
(2ln + lny) = ln(y + -7) + ln(4)

Reorder the terms:
2ln + lny = ln(-7 + y) + ln(4)
2ln + lny = (-7 * ln + y * ln) + ln(4)
2ln + lny = (-7ln + lny) + ln(4)

Reorder the terms for easier multiplication:
2ln + lny = -7ln + lny + 4ln

Reorder the terms:
2ln + lny = -7ln + 4ln + lny

Combine like terms: -7ln + 4ln = -3ln
2ln + lny = -3ln + lny

Add '-1lny' to each side of the equation.
2ln + lny + -1lny = -3ln + lny + -1lny

Combine like terms: lny + -1lny = 0
2ln + 0 = -3ln + lny + -1lny
2ln = -3ln + lny + -1lny

Combine like terms: lny + -1lny = 0
2ln = -3ln + 0
2ln = -3ln

Solving
2ln = -3ln

Solving for variable 'l'.

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

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

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

Combine like terms: -3ln + 3ln = 0
5ln = 0

Divide each side by '5'.
ln = 0

Simplifying
ln = 0
