Martina combined different amounts of water, vinegar, and rubbing alcohol to make 38 milliliters (ml) of a solution for a science experiment. The amount of water was x ml. The amount of vinegar was 8 ml less than that of water, and the amount of rubbing alcohol was half the amount of vinegar. This is represented in the equation below:

x + (x - 8) + one half (x - 8) = 38

What was the difference in the amounts of water and rubbing alcohol Martina combined?

8 ml
