The formula of ball game integration problem is a one-dimensional linear equation.

The integral equation of ball games can be calculated according to the number of games and the integral rules.

For example, if we adopt the integral rule of winning a game and getting a score of X and losing a game, then the total score of each team can be expressed as:

Total score = number of wins ×x+ number of negative fields ×y+ number of flat fields × z.

If the competition is a single round robin, then all participating teams can meet once, and the number of games is:

Number of matches = number of teams × (number of teams-1)/2.

If the competition is a double round robin system, then all teams participating in the competition can meet twice, and the number of competitions is:

Number of matches = number of teams × (number of teams-1).

It should be noted that when calculating the total score, it is necessary to count and calculate the winning and losing times and scores of each game in order to get the correct result.

The general steps to solve a linear equation with one variable are to remove the denominator, remove brackets, shift terms, merge similar terms, and convert the coefficients into 1. Pay attention to the details and error-prone points involved in each step, such as adding brackets after removing the denominator, changing the number when removing brackets, changing the number when moving items, etc. At the same time, we should pay attention to the application of the whole idea in solving the linear equation of one variable.

Matters needing attention in solving linear equation of one variable

1. When removing the denominator, be careful not to omit multiplication. And the denominator is removed, and the fractional line becomes parentheses.

2. When deleting brackets, don't omit every item in brackets, and pay attention to the sign change.

3. Change the logo when moving the project, and be careful not to make mistakes in the logo of the moving project.

4. When merging similar items, the coefficients are added and the letters remain unchanged.

5. Don't reverse the numerator and denominator when the coefficient is 1.
