Question

The sum of the distances two hikers walked is 53mi, and the difference is 25mi. What are the distances? Use a system of equations to solve

Answer 1

39 and 14

Explanation:

A + B = 53

A - B = 25

(Add the two equations together)

2A = 78

A = 78/2 = 39

B = 53 - 39 = 14

Answer 2

a+b=53
a-b=25

2a=78
a=39

39+b=53
b=14
