Applications of Linear Equations - 500 In 2000, the population of Greece was 10, 600, 000, with projections of a population decrease of 28, 000 per year. In the same year, the population of Belgium was 10, 200, 000, with projections of a population decrease 12, 000 people per year. According to these projections, when will the two countries have the same population? What will be the population at that time? 25 years; 9, 900, 000 people Mαth JΣθPARδY!
