this can be an answer!

a. Define your variable.: 
n = number of miles run by Steve

b. Write algebraic expressions for the distances each person ran.: 
n = number of miles run by Steve
n + 4 = number of miles run by Kevin

c. Write an equation that can help you solve the problem.: 
n + (n + 4) = 26

d. Solve the equation.: 
n + (n + 4) = 26
n + n + 4 = 26
2n + 4 = 26
2n = 22
n = 11 number of miles run by Steve
n + 4 = 11 + 4 = 15 number of miles run by Kevin 

e. Check your answer.:
n + (n + 4) = 26
n = 11
11 + (11 + 4) = 26
11 + (15) = 26
11 + 15 = 26
26 = 26 The identity indicates that the value n = 11 is correct.
