I am not great at this stuff, but you need to start by writing out how many of each element there are in the product and in the reactions. It is a lot of math and trying to make the equal on both sides

have a look at the picture i’ve attached to see if it helps, let me know if you want me to go over it in more detail and i will tomorrow morning :)
