Question

There are students in three rows taking a test. there are 22 students in the first row, 19 students in the second row, and a certain number of students in the third row. if there are a total of 62 students, how many students are in the third row?

Answer 1

22+19+x = 62
combine like terms

41+x = 62
subtract 41 from both sides

x= 21
there are 21 students in the third row
