Pair Of Linear Equations In Two Variables
The students of a class are made to stand in rows. If 3 students are extra in a row, there would be 1 row less. If 3 students are less in a row, there would be 2 rows more. Find the number of students in the class.
Let the number of rows be x and number of students in a row be y.
Total students of the class
= Number of rows × Number of students in a row
Using the information given in the question,
Total number of students = (x − 1) (y + 3)…
