Answer:

x = 5

Step-by-step explanation:

Your statement says, "the log to the base 2 of 3x - 7 is 3" and you want to find the value of x.

Here the base is 2, obviously.

 log to the base 2 of 3x - 7                        3

2                                                  equals   2

and this simplifies to 3x - 7 = 8.  Adding 7 to both sides, we get 3x = 15.

Thus, x must be 5.
