Solve the equation
log(5x)-log(x-3)=1

x = 6

Step-by-step explanation:

Using the rules of logarithms

• log x - log y ⇔ log ( )

• x = n ⇔ x =

Given

log(5x) - log(x - 3) = 1

log ( ) = 1, then

= = 10 ( cross- multiply )

10(x - 3) = 5x

10x - 30 = 5x ( subtract 5x from both sides )

5x - 30 = 0 ( add 30 to both sides )

5x = 30 ( divide both sides by 5 )

x = 6

x =6

Step-by-step explanation:

log(5x) - log(x - 3) = 1

Recall that  the logarithm of a fraction is the difference of the logarithms,

so, the difference between two logarithms is logarithm  of the fraction. Then,
