I got 82 points in Chinese, 95 points in English and 87 points in moral character. My math score is 9 points higher than the average score of four courses. How many points did I get in the math exam?
Can be solved by equation:

Solution: If the average score is X, the math score is (X+4).

Equivalence relationship: total score of four courses = average score *4.

[82+95+87+(X+9)]=4X

264+9+x=4X

273+X=4X

3X=273

X=273/3

X=9 1

Math score: X+9=9 1+9= 100.
