Describe the error in solving the equation for a.
12-2x=-2(y-x)
-2x=-2(y-x)-12
x=(1-x)+6
O In the third step, the left side was not divided by -2 correctly.
In the third step, the negative sign was not distributed to both terms in
parentheses.
The equation is not solved for a because there is still a term with a on both
sides.
The equation cannot be solved for a because the terms with a cancel out on
each side.
Correct the error.
