Step 1: Rewrite the FD into those with only one attribute on RHS. We obtain:

{{attribute}}        {{attribute}}   

Step 2: Remove trivial FDs (those where the RHS is also in the LHS). We obtain:

{{attribute}}        {{attribute}}   

Step 3: Minimize LHS of each FD. We obtain:

{{attribute}}        {{attribute}}   

Step 4: Remove redundant FDs (those that are implied by others). We obtain:

{{attribute}}        {{attribute}}
