Solve the following logarithmic equations
log(10x + 5) − 3 = log(x − 5)

Step-by-step explanation:

Rewrite the equation, adding 3 to both sides and subtracting log(x-5) from both sides:

Using the next propierty:

Using this propierty:

Cancel logarithms by taking exp of both sides:

Multiplying both sides by x-5 and factoring:

Solving for x multiplying both sides by

the 4th choice is the correct one
