5. There are 84 students in class 1 and class 2. There are 58 students in 5 / 8 of class 1 and 3 / 4 of class 2? How many points are there for class 1 in 5 years more than Class 2 in 5 years, and how many points are there for class 2 in 5 years less than Class 1 in 5 years?

The number of one class is x, and the number of two classes is y
Set of equations 1) x + y = 84
2) 5 / 8x + 3 / 4Y = 58, x = 40, y = 44
There are 40 people in class 1 and 44 people in class 2
