$$\stackrel{\leftrightarrow}{A} \cdot \vec{b} = \stackrel{\leftrightarrow}{C} : \vec{d}$$

I'd like to know which one is correct form

1.) $$ \vec{b} = (\stackrel{\leftrightarrow}{A})^{-1} ( \stackrel{\leftrightarrow}{C} : \vec{d} ) $$

2.) $$ \vec{b} = (\stackrel{\leftrightarrow}{A})^{-1} \cdot ( \stackrel{\leftrightarrow}{C} : \vec{d} ) $$

3.) None of the above, in this case what would be the correct form?
