by dy/dx, we'll be assuming that "y" is encapsulating a function, a function in terms of "x".

Answer:
8 students
Step-by-step explanation:
72 slices of pizza and 80 cookies were purchased after a school program
Each student will get an equal numbert of both pizza and cookies
72/8
= 9
80/8
= 10-1
= 9
Hence 8 students can attend the after tutoring program
It would be irrational, there is a math calculator called math papa if you need to check your answer
3x+3x-5= 1
6x-5=1
Whenever moving a number, the sign always changes.
6x-5+5= 1+5
6x= 1+5
6x= 6
divide both sides by 6
6x/6= 6/6
x= 1
Check solution by using the substitution method
3(1)+3(1)-5=1
3+3-5=1
6-5= 1
1=1
Answer: x=1
