can anyone help mesolve this;

Question

ln(x+9)-ln x =1

thanks in advance guys!

Answer 1

ln(a)-ln(b)=ln(a/b)

ln(x+9)-ln(x)=1

ln[(x+9)/x]=1

anti-logarithm of that:

(x+9)/x=e

e=2.718281828459045235360287471

x+9=e*x

x-e*x= -9

x*(1-e)= -9

x= -9/(1-e)

x= -9/(1-2.718281828459045235360287471)
x= -9/-1.718281828459045235360287471
x= 5.2377903618239378194650180459811
