Question

Each day, the number of births in the world exceeds the number of deaths by 22 thousand. the combined number of births and deaths is 274 thousand. determine the number of births and the number of deaths per day.

Answer 1

b + d = 274,000
b = d + 22,000

(d + 22,000) + d = 274,000
2d + 22,000 = 274,000
2d = 274,000 - 22,000
2d = 252,000
d = 252,000/2
d = 126,000 <=== number of deaths

b = d + 22,000
b = 126,000 + 22,000
b = 148,000 <=== number of births
