suppose Peter is now x years old
if John is 12 years older than his brother Peter, then John is x%2B12
four years ago Peter was x-4 years
if John was three times as old as Peter was then,then John is 3%2A%28x%2B12-4%29=3%28x%2B8%29

so, your answer is: [3] Four years ago %28x+-4%29+=+3%28x+%2B+8%29
