The combined land area of the countries A and B is 157,973 square kilometers. Country A is larger by 773 square kilometers. Determine the land area of each country.
now its just a matter of subbing (B + 773) + B = 157,973 2B + 773 = 157,973 2B = 157,973 - 773 2B = 157,200 B = 157,200/2 B = 78,600 <=== land area for country B
A = B + 773 A = 78,600 + 773 A = 79,373 <== land area for country A
