Find the error in the problem below19 - 2k = 3k - 1     +3k   +3k19 + 1k = -1-19           -19k = -20
  • They should have divided by 1 for the last step
  • They should add 19 instead of subtracting 19
  • I can not find an error
  • Instead of adding 3k they should subtract 3k
Find the ErrorWhat error did the student make when solving the equation:1/5x + 6 = 3/5x + 51x + 6 = 3x + 5-2x + 6 = 5-2x = -1x = 1/2

Find the ErrorWhat error did the student make when solving the equation:5x + 6 =  665x - 6 = 66 -65x = 605*5x= 60*5x = 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
