given:
Halley's Comet appears about every 75 years.
One appearance was the year Mark Twain was born.
Let this year be x
The next appearance was the year he died.
Since Halley's Comet appears about every 75 years, means that Mark Twain lived 75 years too and died in year y+=+x%2B75
The sum of these two years is 3745.
x%2B%28x%2B75%29+=+3745
2x+%2B+75+=+3745
x+=+%283745-+75%29%2F2
x+=+1835 the year Mark twain was born
y+=+x%2B+75
y+=+1910 In year 1910 Mark Twain died.
