Answer:Nathan tide 2 miles
Explanation:
Let x represent the number of miles that Nathan rode.
Let y represent the number of miles that Miguel rode his bicycle.
Miguel rode his bicycle 4 miles less than 5 times the number of miles that Nathan rode. This means that
y = 5x - 4
If Miguel rode his bicycle 6 miles, then y = 6
Therefore, the number of miles that Nathan rode his bicycle would be
6 = 5x - 4
5x = 6 + 4 = 10
x = 10/5 = 2 miles
