<h2>Hello!</h2>

The answer is:

Garyn would plant the garden by himself in 6 hours.

From the statement, we know that Frankie can plant a garden by herself in 10 hours, but with her son's help(Garyn), they are able to do it in 4 hours.

If they are able to do the work in just 4 hours, it means that that they are able to do it in 6 hours less than Frankie working alone.

$10hours-4hours=6hours$

Then, let be 10 hours, the Frankie's rate "x" and the Garyn's rate "y", so:

$x-4Hours=y\\$

If x is equal to 10:

$10hours-4hours=y\\$

$6hours=y\\$

So, Garyn would plant the garden by himself in 6 hours.

Have a nice day!
