Solve the following equations.
1 − log8(x − 3) = log8(2x)

The answer to your question is: 4

Step-by-step explanation:

Data

                                   1 − log₈(x − 3) = log₈(2x)

                                   1 = log₈(x − 3) + log₈(2x)

                                    1 = log₈ 2x(x - 3)

                                    8¹ = 2x(x - 3)

                                    8 = 2x² - 6x

                                    2x² - 6x - 8 = 0

Factorize                      2x² - 8x + 2x - 8 = 0

                                    2x(x - 4) + 2(x - 4) = 0

                                    (x - 4) (2x + 2)

                 x1 = 4                      x2 = -2/2 = -1

x2 = -1 is not and answer because there are not negative logs.
