Look at the problem and work shown. in which line was an error made and what should have been done differently? seven less than 5 times a number is 62. what is the number? 7 – 5n = 62 (line 1) 7 – 7 – 5n = 62 – 7 (line 2) –5n = 55 (line 3) –5n ÷ 5 = 55 ÷ 5 (line 4) n = –11 (line 5)

Hey there :)

Let us first translate the sentence into mathematics!

Seven less than 5 times a number is 62
Less than means minus
seven less than is 'something - 7'
"Is" is where = sign comes

Let n represent a number

5n - 7 = 62

Take 7 to the other side [ Add when you see minus sign ]
5n - 7 ( + 7 ) = 62 + 7
5n = 69

Take 5 to the other side in order to isolate n [ Divide when you see multiplication sign ]
5n ÷ 5 = 69 ÷ 5
n = 13.8

Therefore, we can notice that the error has occurred in the first line
