log(x+5)-logx=3
log(1/x)+log(x+5)= 3
log((x+5)/x)= 3 now take exponent on both sides to get rid of log
(x+5)/x= e^3 multiply both sides times x:
x+5= e^3x subtract 5+e^3 from both sides
(1-e^3)x= -5
Divide both sides by 1-e^3:
x= -5/(1-e^3)

Solve the equation.
log(x+5)-logx=3
log (x + 5) – log x = 3

------- Converting to EXPONENTIAL form

1,000x = x + 5 ----- Cross-multiplying
1,000x – x = 5
999x = 5_______
