SOLUTION: in a 10 kilometer race there are 112 more men entered than women. Find the number of female runners if the total number of runners in the race is 600
Let x = the number of men, y = number of women.
x + y = 600,
x - y = 112.
Can you solve this system? (Hint: add the two equations, both left and right sides).
Answer. x = 356, y = 244.
