Solution for ln(x+4)+ln(x-1)=0 equation: 


Simplifying
ln(x + 4) + ln(x + -1) = 0

Reorder the terms:
ln(4 + x) + ln(x + -1) = 0
(4 * ln + x * ln) + ln(x + -1) = 0
(4ln + lnx) + ln(x + -1) = 0

Reorder the terms:
4ln + lnx + ln(-1 + x) = 0
4ln + lnx + (-1 * ln + x * ln) = 0
4ln + lnx + (-1ln + lnx) = 0

Reorder the terms:
4ln + -1ln + lnx + lnx = 0

Combine like terms: 4ln + -1ln = 3ln
3ln + lnx + lnx = 0

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

Solving
3ln + 2lnx = 0
