Respuesta :

Answer:

Kaitlin's answer is wrong because she is supposed to by dividing. When trying to get rid of a number from a variable you have to divide the number by itself and whatever you do to one side you have to do to the other side

so you would do 5/5 - cancels out

15/5=3

y=3

Step-by-step explanation:

have a great day :D

Answer:

  • y = 3

Explanation (Part A):

  • She was supposed to divide five both sides. However, she divided one side by five and multiplied five on the other side, which makes her answer incorrect.
  • She got confused that if any side is divided by a number, the other side must be divided by that same number.

Solution (Part B):

  • 5y = 15
  • => 5y/5 = 15/5
  • => y = 3

The correct answer must be 'y = 3'.
