Help me with this RICE table? I don't know where I went wrong.?

I'm doing my chemistry homework and I can't really understand where I went wrong with this problem. I am fine re-doing it, I just need to know my mistake. For the hypothetical reaction AX2 <--> A + X2 Kc = 1.50 If the reaction container starts wit [AX2]=0.100 and [X2] =0.0500 and no A,... show more I'm doing my chemistry homework and I can't really understand where I went wrong with this problem.

For the hypothetical reaction AX2 <--> A + X2 Kc = 1.50

If the reaction container starts wit [AX2]=0.100 and [X2] =0.0500 and no A, What is the [A] at equilibrium?
