Question

PLEASE HELP i need to know which proof contains an error

Answer 1

Step 6

Explanation:

From the given proof, consider Step 5 given below:

`m_T=((b-a)-b)/(c)`

By simplifying this step, we get the following results:

`m_T=(b-a-b)/(c)=(b-b-a)/(c)=-(a)/(c)`

However, in the statement of Step 6, the result is given as a/c.

Thus, Step 6 of the proof contains an error.
