The combined land area of the countries A and B is 170,973 square kilometers. Country A is larger by 473 square kilometers. Det

MAVERICK [17]

$A+B=170,973$

A is larger by $47 km^{2}$

The equation is $(B+473)+B=170,973$

Subtract 473 from each side and add the B's

$B+473-473+B=170,973-473$

$2B=170,500$

Now divide the number by the variable.

$170,500$ ÷ $2=85,250$

$B=85,250$

To check, replace the B's with the value.

$(85,250+473)+85,250=170,973$

$85,723+85,250=170,973$

Answer:

County A= $85,723km^{2}$
County B= $85,250km^{2}$
