Question

the combined land area of the countries a and b is 132,973 square kilometers. country a is larger by 573 square kilometers. determine the land area of each country

Answer 1

`the combined land area of the countries a and b is 132,973 square kilometers`
so, a+b = 132973

Answer 2

`country a is larger by 573 square kilometers`
meaning that
(area of country A) = (area of country B) + 573
a = b + 573

Answer 3

Please choose variables, such as a and b, or A and B, to represent the respective areas of these two countries. Then write the relevant equations relating these variables to each other.

Answer 4

the system of equations is therefore

a+b = 132973
a = b + 573

Answer 5

thats the answer jim thompson?

Answer 6

You need to solve for a and b :-)

Answer 7

thats where i get lost lol

Answer 8

im very sorry

Answer 9

Replace a in the first equation:

a + b = 132, 973

with b + 573, because a = b + 573

Answer 10

a + b = 132, 973

b + 573 + b = 132, 973

Answer 11

do i divide next at all?

Answer 12

Now subtract 573 from both sides,

simplify,

then divide both sides by 2.

This will give you the value for b.

Answer 13

Got it?

Then substitute back to get the value for a.
