Find the Error
What error did the student make when solving the equation:
5x + 6 =  66
5x - 6 = 66 -6
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
