Answer:
3x-y=6?
Step-by-step explanation:
The correct option is: x = 1Explanation:Although there are two solutions to the equation are given: -8 and +1, the true solution will be the one that satisfies the given equation. If we put "-8" into the equation

, the equation will not satisfy as the log of the negative number does not exist. If we put "+1" in the above equation, we would get "3" as an answer, meaning the true solution exists.
Hence the correct option is "x=1"
Answer:
12% of 50 is the same as 50% of 12
50% of 12 is 0.5 * 12 = 6
So six is the correct answer.
