The average score of Chinese mathematics is 98, the average score of Chinese foreign language is 93, and the average score of mathematics foreign language is 95. How did you do in the three subjects?
Method 1 solution: if the Chinese score is x, the math score is (98*2)-x= 196-x ①.

According to the second condition, the foreign language score is (93 * 2)-X = 186-X2.

According to the third condition, 196-x+ 186-x=95*2, then x=96.

If you substitute ①, the math is 100; if you substitute ②, the foreign language is 90.

Answer: 96 points for Chinese, 90 points for foreign languages and 0/00 for mathematics.

Method two solution: let math x, foreign language y and Chinese z.

Then x+z=98*2.

y+z=93*2

x+y=95*2

X= 100,y=90,z=96。

Answer: 96 points for Chinese, 90 points for foreign languages and 0/00 for mathematics.

Method 3: Chinese score: (98 * 2+93 * 2-95 * 2)/2 = 96.

Math score: 98*2-96= 100.

Foreign language score: 95*2-96=90

Answer: 96 points for Chinese, 90 points for foreign languages and 0/00 for mathematics.
