I don't think this is possible to answer. It doesn't have any picture showing, nor does it say any area numbers.
The final answers would be x=-5 x=9
Answer:
Step-by-step explanation:
Student : teacher = 5 : 2
Number of students = 5x
Number of teachers = 2x
<u>Last year:</u>
Last year Total = 56
5x+ 2x = 56
7x = 56
x = 56/7
x = 8
Number of students = 5*8 = 40
Number of teachers = 2*8 = 16
<u>This year:</u>Total = 70
5x + 2x = 70
7x = 70
x = 70/7
x = 10
Number of students = 5*10 = 50
Number of teachers = 2*10 = 20
