Balancing UDMH with N2O4. HELP

[mimsy]

__H₂N-N(CH₃)₂(l) + __N₂O₄(l) = __CO₂ (g) + __H₂₀(g) + __N₂ (g)

I've tried multiple times to balance this one but each one is unbalanced. The only thing I've figured out is 2 N₂O₄ is right.

Also, no idea what's going on with H₂N-N(CH₃)₂(l). not sure what that means

Its an Oxidation.

H₂N-N(CH₃)₂(l) + 2 N₂O₄(l) = 2 CO₂ (g) + 4 H₂O(g) + 3 N₂ (g)

thanks!! i ended up finding a solution and it’s the same as urs
