Solution for ln(x-5)+ln(x+8)=0 equation:


Simplifying
ln(x + -5) + ln(x + 8) = 0

Reorder the terms:
ln(-5 + x) + ln(x + 8) = 0
(-5 * ln + x * ln) + ln(x + 8) = 0
(-5ln + lnx) + ln(x + 8) = 0

Reorder the terms:
-5ln + lnx + ln(8 + x) = 0
-5ln + lnx + (8 * ln + x * ln) = 0
-5ln + lnx + (8ln + lnx) = 0
