Have fun with math as you solve the integer number for the question mark:
🌻 = 2 X 🐷 - 12
🦤 + 🐷 = 🌻 + 9
🦤 + 🌻 = 6
🐷 + ? = 9 -
Fill each column with the digits 1 through 6 without repeating or omitting digits so the sums in the right column are the total of each row. A digit may appear more than one across rows.
