Question

The following shows steps by three students Sting, Stewart and Andy to solve the equation:
-6.5=-1/2 (X+3)-10. One of the three students solving the equation correctly. Use this information for problems 15 and 16.

Sting: -6.5=-1/2 (X+3)-10
-6.5=-1/2 X+3/2-10
-6.5=-1/2 X+ 8.5
-15=-1/2 X
30=X

Stewart: -6.5=-1/2 (X+3)-10
-6.5=-1/2 X-3/2-10
-6.5=-1/2 X-11.5
5=-1/2 X
-10=X

Andy: -6.5=-1/2 (X+3)-10
13=X+3-10
23=X+3
20=X

Which of the students solving the equation correctly? How do you know without solving the equation that the student you specified is correct? Show this.

Where did the other two students go wrong? Be specific and use words to explain. Do not just highlight or use an arrow
