In order to realize the balanced development of regional education, it is urgent for our city to solve the weak A and weak B problem of a county with a one-dimensional linear equation. ...
Solution: It costs X million yuan to rebuild a Class A school and (230-X)/20,000 yuan to rebuild a Class B school.
List the equation according to the meaning of the question: 2x+(230-x)/2=205.
2x+115-x/2 = 205 3/2x = 205-153/2x = 90x = 60 (230-x)/2 = 85a: It costs 600,000 yuan to build a class A school.
