Answer:
No, it does not.
Step-by-step explanation:
5 [tex]\neq[/tex]11 , so 8 is not the solution. Her work didn't describe how she got the answer she did. The work she could have showed would have looked like:
s-3=11
[move the three to the other side with addition]
s= 3+11
s=14
therefore, her answer should have been 14, and the work she did show was inadequate for the answer she gave.
