The total number of students in the seventh grade is 9 more than 4 times as many students as are in the art class. there are 101 student in the seventh grade write and solve a equation to find the number of stupidest in the art class l. let x represent the number of stupids in the art class

I'm assuming you mean students when you write stupids. 

Give that x = students, the number of total students is equal to 9 more than 4 times x or: 

4x + 9

Set that equal to 101 and solve. 

The answer is 23
