3,1,3,1

Explanation:

 Reaction equation:

    HBr    +    Al(OH)₃   ⇒    H₂O    +     AlBr₃

To balance an equation we make sure that the same number of atoms appears on both sides of the expression.

  HBr    +    Al(OH)₃   ⇒    H₂O    +     AlBr₃

Let us a simple mathematical method to solve this problem

  aHBr    +    bAl(OH)₃   ⇒    cH₂O    +     dAlBr₃

  a, b , c and d are the coefficients that will make the equation balanced;

 Conserving H;  a + 3b = 2c

                      Br;  a  = 3d

                      Al;   b  = d

                       O;    3b  = c

    let us make a = 1

                         d = \frac{1}{3}

                         b = \frac{1}{3}

                          c = 1

multiply through by 3;

     a = 3, b = 1, c= 3 and d = 1
