Hello Mathematica Friends

If we have an array variable, and assuming after intermediate calculations, some equations are found to be below.

eqn1=10. A[[1,1]]+b A[[1,1]]+c A[[1,2]]+3. A[[1,2]] (only for illustration)

Simplify[] does not combine the coefficients under same array member, i.e. instead of (10.+b)A[[1,1]]+(c+3.)A[[1,2]], it is showing the earlier mentioned form.

Is there a way to collect them and simplify them. But when I checked for simple cases, Simplify[] seems to work.

Thanks for the suggestions.
