Is there any function like Solve but designed to deal with matrix equations? Something like:

mA = {{1, 2}, {3, 4}};
mC = {{19, 22}, {43, 50}};
Solve[mA.mX == mC, mX]  (* should return {{5, 6}, {7, 8}} *)

I know that you could just type

Inverse[mA].mC

but I'm curious if there is other way to do this.

$\begingroup$ 
mA = {{1, 2}, {3, 4}};
mC = {{19, 22}, {43, 50}};
mX = Array[X, {2, 2}]
Solve[mA.mX == mC, Flatten[mX]]

Will do what you want
