Using a system of equations, it is found that:
b) The domain of the solution is that Steve ran 11 miles.
c) Variable S gives the distance ran by Steve.
d) The algebraic expressions are: K = 4 + S, K + S = 26.
e) The equation is: 4 + S + S = 26.
A system of equations is when multiple variables are related, and equations are built to find the numeric values of each variable, according to the relations built in the problem.
In the context of this situation, the variables are given as follows:
Kevin ran 4 miles more than Steve ran, hence:
K = 4 + S.
The sum of their distances is 26 miles, hence:
K + S = 26.
Replacing the first equation K = 4 + S on the second, we have that:
4 + S + S = 26
2S = 22
S = 11 miles.
