Let A represent the number of marbles Allan has and let X represent the number of marbles Alex has. From the given information, we have the equations A + X = 76 and A = X + 12. Substituting the second equation into the first, we get (X + 12) + X = 76. Solving for X, we find that X = 32. Therefore, Allan has A = X + 12 = 32 + 12 = 44 marbles.
