1.2 free throw, 13 2-pointer; 4 free throw, 12 2-pointer; 6, 11; 8, 10; 10, 9; 12, 8; 14, 7; 16, 6; 18, 5; 20, 4; 22, 3; 24, 2; 26, 1
2.2 two points, 4 three points; 5 two points, 2 three points

There are several mathematical problems of linear equation of two variables
B (B is not equal to 0) is the root of the equation x * x + CX + B = 0, then what is B + C equal to
Why

Substituting B into the original equation, b * B + BC + B = 0
The transformation is: B (B + C) = - B
b+c=-1

Several mathematical problems. Binary linear equation!
1. Find the positive integer solution of the quadratic equation 3x + 2Y = 11. (fill in the blanks, only the right number is required) 2. Use 190 sheets of iron to make a box, each sheet of iron to make 8 bodies or 22 bottoms, one fit and two bottoms to form a complete box. How many sheets of iron can make the box body and how many bottoms can make a batch of complete boxes, Using the system of linear equations of two variables to solve)

X = 1, y = 4 and x = 3, y = 1.2. Answer: 110 body and 80 bottom. Let X be used as the body and y be used as the bottom. A.8x = 22y / 2 the bottom is twice as much as the body. B.x + y = 190 the iron sheet is 190. C. calculation: x = 190-y from B. substituting a to get 8 (190-y) = 11y, then y = 80 and substituting C to get a = 110
