This is really bugging me. Up until these last few problems in the textbook, O of O was pretty easy for me. So I figure the thing I'm not getting can't be too tough. But class was cancelled today and I want to get this solved so I can get on with things. Anyway, here it is:

4{[5 (x-3) +2] -3[2(x+5)-9]}

The answer according to the textbook is -4x -64 but I'm not coming up with it.

Any help is greatly appreciated. Thanks!
