Haley's error seems to be failing to distribute the 1/2 properly when she eliminated parentheses. Apparent, she incorrectly decided that ...
1/2(6 -x) ⇒ 3 -x . . . . instead of 3 -1/2x
Then when -x was added to +3x, she got 2x. Had she done it properly, she would have added -1/2x to +3x to get 5/2x.

<em>Additional comment</em>
It is a common error to "distribute" the factor outside parentheses to the first term only, as Haley apparently did. Another common error is to fail to distribute minus signs properly. The distributive property requires you apply the outside factor to <em>all</em> of the terms inside parentheses.
Answer:
Step-by-step explanation:
<u>Given information</u>
<u>Derived expression from the given information</u>
<em>Presumably, I think this is a combination of segments</em>
<u>Substitute values into the given expression</u>
<u>Combine like terms</u>
<em>The following is the expression</em>
<u>Subtract 3 on both sides</u>
<u>Subtract x on both sides</u>
<u>Substitute the x value into corresponding expressions to determine the final value</u>
Hope this helps!! :)
