Total score of Chinese and mathematics 173. Total score of Chinese and English 162. Total score of mathematics and English 165. How to calculate the scores of three courses?

According to the meaning of the question, the equivalence relation can be listed:

① Chinese+Mathematics = 173

② Chinese+English = 162

③ Mathematics+English = 165

Add up the above three equations to get: 2 (Chinese+Mathematics+English) =500.

Therefore, Chinese+Mathematics+English =250.

Subtract Equation ① from the above formula to get English =250- 173=77 (points).

Subtract Equation ② from the above formula to get the math =250- 162=88 (points).

Subtract equation ③ from the above formula to get language =250- 165=85 (point).

You can also set your Chinese score as A, your math score as B, and your English score as C.

Then a+b= 173.

a+c= 162

b+c= 165

Add the three formulas to get 2(a+b+c)=500.

a+b+c=250

So c=250- 173=77 (point)

B=250- 162=88 (point)

A=250- 165=85 (point)

These two algorithms are the same, I hope I can help you.
