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'.
