You can put this solution on YOUR website!

Let x = the nephew's age now
Then 3x = John's age now
Then x-4 = the nephew's age 4 years ago
and 3x-4 = john's age 4 years ago

Then write and solve the equation that says John's age 4 years ago was 4 times his nephew's age 4 years ago:
3x-4+=+4%28x-4%29

You can finish from there....
