Solve the equation below:

ln x - ln 5 = - 1

x = 5/e

Step-by-step explanation:

ln x - ln 5 = - 1

We know that ln a - ln b = ln (a/b)

ln x - ln 5 = - 1

ln (x/5) = - 1

Raise each side to the power of e

e^ ln (x/5) = e^-1

We know that e^-1 = 1/e

x/5 = 1/e

Multiply each side by 5

x/5 * 5 = 1/e * 5

x = 5/e
