Solve the equation LaTeX:  \displaystyle \log_{7}(x + 360)-\log_{7}(x + 66)=1 .

Using the quotient property of logarithms gives LaTeX:  \displaystyle \log_{7}\frac{x + 360}{x + 66} = 1 . Making both sides of the equation exponents on the base LaTeX:  \displaystyle 7 gives LaTeX:  \displaystyle \frac{x + 360}{x + 66}=7 . Clearing the fractions by multiplying by the LCD gives LaTeX:  \displaystyle x + 360=7 x + 462 . Isolating LaTeX:  \displaystyle x gives LaTeX:  \displaystyle x = -17 .
