FRODO AND SAM are 17 miles apart and are walking towards each other they meet in 4hrs. find frodos rate if frodo walks 1mph faster than sam.

The equation that I get from this is:

x+(x+1)x4=17

if you solve it, Frodo's equation would be the (x+1) as it is 1 mph faster than Sam (x). Does that help?
I think you will get a better result from

(x + x+1)4=17

It's confusing if you use x for both multiplication and a variable.

And, as we are looking for Frodo's rate, I'd use

4(f + f-1) = 17
