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.
