Had no problem with the other problems but this one though, the prof said we should add up the nitrogen from the right after multiplication. So that'll make it 12×1=12+1=13 which made it unbalanced,

If all else fails, just set up a linear system and solve it.

system of equations doesn't work here because substituting alpha for 4 gamma in the oxygen equation would only work if delta was 0

Doing it element by element in this case is a waste of time, NH3 and NO3 don't get transformed

Yeah because the anon made a typo and wrote NH3 instead of NO3, so his equation is nonsense.
works just fine in the original equation

exactly, linear systems work very well to solve non-redox equations, this particular solution is wrong tho
