Question

Read the following prompt and type your response in the space provided.

Look at the problem and work shown. In which line was an error made and what should have been done differently?

Six less than 4 times a number is 50. What is the number?

6 – 4n = 50 (line 1)

6 – 6 – 4n = 50 – 6 (line 2)

–4n = 44 (line 3)

–4n÷ –4 = 44÷ –4 (line 4)

n = –11 (line 5)
.

Answer 1

Answer: Line 1

Explanation:

Without looking at the context given, everything seems to be normal, everything is correct. Inputting n = -11 into line 1 makes it true. But when we take a look at the context given, we can see that the equation that it said "6 less than 4 times a number" meaning we were supposed to take 6 and subtract it from 4 times the number, meaning the actual equation is

4n - 6 = 50

Therefore, line 1 made an error
