Can you solve it if I write the same thing like this ?

                   s    +    12
                 3s    -      8
                =========  


The piece on the left is
                                            s
                                          3s
                                      ====
                                          4s   .

The piece on the right is
                                           12
                                          -  8
                                        ====
                                             4  .

Write the pieces together again, and you have

                                   4s + 4
