- 10. Multiple ChoiceFind the error in the problem below
19 - 2k = 3k - 1
+3k +3k
19 + 1k = -1
-19 -19
k = -20They should have divided by 1 for the last stepThey should add 19 instead of subtracting 19I can not find an errorInstead of adding 3k they should subtract 3k - 11. Multiple ChoiceWhat is the second step to solve this equation:
11 - 3x = 44Add 3 to both sidesSubtract 11 from both sidesAdd 11 to both sidesDivide -3 on both sides. - 12. Multiple Choice3/8 d = 1/42/3- 2/31/3-1/3
- 13. Multiple ChoiceFind 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 = 300The student subtracted 6 from both sides instead of addingStudent multiplied by 5 instead of dividing by 5Student got the wrong answer when subtracting 66-6The student did not correctly eliminate the variable from one side of the equation - 14. Multiple Choice
