3. Reasoning Ben says that n = 5 is the solution of the equation 7n = 45. How can you check whether Ben is correct?

likoan [24]

Answer:

You cant, because Ben is WRONG, unless you made a typo while writing the question

Step-by-step explanation:

If you subsitute N for 5, then the equation would be 7 x 5 = 45. However, this is not true. The correct equation is 7 x 5 = 35, so Ben is wrong UNLESS you made a typo while writing the question.

Hope this helped! If it did, please mark it brainliest! It would help a lot! :D
