Czechoslovakia 17233

Slovakia has an area 38% smaller than the Czech Republic. Original Czechoslovakia had an area of ​​128,000 square kilometers. What are the areas of both states?

Correct answer:

c =  79012.3457
s =  48987.6543

Step-by-step explanation:


c+s = 128000
s = c -38/100·c

c+s = 128000
62c-100s = 0

Pivot: Row 1 ↔ Row 2
62c-100s = 0
c+s = 128000

Row 2 - 1/62 · Row 1 → Row 2
62c-100s = 0
2.61s = 128000


s = 128000/2.61290323 = 48987.65432099
c = 0+100s/62 = 0+100 · 48987.65432099/62 = 79012.34567901

c = 79012.345679
s = 48987.654321
