Question

the combined land area of the countries a and b is 188973 square kilometers. country a is larger ny 673 square kilometers. determine the land area of each country

Answer 1

x+y=18897

x=y+673

2y+673 = 18897

2y = 18224

y= 9112

x = 9112+673 = 9785

9112 + 9785 = 18897

so one country is 9112 and the second country is 9785
