Since x is in an absolute value equation, it means it could be negative or positive. In order to get three from adding to 1, 2 is one, but because of the absolute value, if you make x -4 then it would be -3 but the absolut value would make it 3. Your answer is both -4 and 2

To find how many ounces you need to make, you multiply the number of packs by how many ounces.
So, it would look like:
