Answer:

oooo sorry I am really very sorry I

Answer 2

Answer:

The correct answer is c) 48

Step-by-step explanation:

Let the number of students = y

Let the number of benches = x

From the first statement

y = 4x - 12 (three empty benches * 4 students)

From the second statement

y = 3x + 3

Substituting equation 2 into equation 1

3x + 3 = 4x - 12

Rearranging..

x = 15

Substituting the value for x in equation 2

y = 3(15) + 3 = 48
