Question

The combined land area of the countries A and B is 131,973 square kilometers. Country A is larger by 473 square kilometers. Determine the land area of each country.

Answer 1

x+y=131973

x=y+473

2y+473 = 131973

2y = 131500

y= 65750

x= 65750 + 473 = 66223

65750 + 66223 = 131973

so one country is 65750 and the second country is 66223
