Find the Error

What error did the student make when solving the equation:

5x + 6 = 66

5x = 60

5*5x= 60*5

x = 300

• The student subtracted 6 from both sides instead of adding

• Student multiplied by 5 instead of dividing by 5

• Student got the wrong answer when subtracting 66-6

• The student did not correctly eliminate the variable from one side of the equation
