X + y = 13......x = 13 - y
2x - 3y = 1
2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5
x + y = 13
x + 5 = 13
x = 13 - 5
x = 8
<span>so, x = 8 and y = 5</span>

14 miles
Step-by-step explanation:
Assuming each horse was only ridden once
then a total of 13 horses were ridden for a total of 182 miles
182 miles
/ 13 horses = 14 miles horse
Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.
Note that the fact that there were 3 riders is irrelevant.
