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)

The equation would be
4n-6=50
4n=50+6
4n=56
n=56/4
n=14
