Let x stand for Saturday.

Let y stand for Sunday.

Then we know:

and

Then we can just use substitution to solve this system of equations.

And of course, if y is 3.25, then:

So we know that Saturday, he walked 4.75 miles,

and Sunday he walked 3.5 miles.

You could use trial and error to solve this, but this is why Algebra is so useful.

I hope this helps! Keep practicing! :)
