A college has two classrooms of students. • Classroom A had 70 students.
• Classroom B had 30 students.
• Classroom A sent groups of 4 students to Classroom B until both classrooms had the same number
of students.
The equation shown can be used to find the number of groups that Classroom A sent to Classroom B so
each classroom had the same number of students.
70 - 4x = 30 + 4x
How many groups did Classroom A send to Classroom B?
