    No those answers are incorrect 1 Variable = x . That is the number of miles that Mgiuel ran 2. number of miles Chris ran is x + 4 3 x + (x + 4) = 18 2x + 4 = 18 x = 14/2 = 7 Miguel ran 7 miles

    14 miles for miguel cannot be correct That would mean that Chris ran 14 + 4 = 18 miles which is the total of what they both ran. Its 7 for miguel and 11 for Chris
