Let the number in China be x.
USA has 115 000 more than China = x + 115000
Total = 505 780
x + (x + 115000) = 505780
x + x + 115000 = 505780
2x + 115000 = 505780
2x = 505780 - 115000
2x = 390780
x = 390780/2
x = 195 390
So China is x , 195 390, USA = x + 115000 = 195390 + 115000 = 310390
China = 195 390
USA = 310 390
Hope this clarifies it.

2x + 115,000 = 505280
2x = 390,780
x = 195,390
America = x + 115,000 =
310,390
China = x =
195,390
Just to check, 310,390 + 195,390 = 505,780.
