Answer
Incomplete solution.
Work Step by Step
The given equation is
$12-2x=-2(y-x)$
Subtract $12$ from each side.
$12-2x-12=-2(y-x)-12$
Simplify.
$-2x=-2(y-x)-12$
Divide each side by $-2$.
$\frac{-2x}{-2}=\frac{-2(y-x)-12}{-2}$
Simplify.
$x=(y-x)+6$
Add $x$ to each side.
$x+x=y-x+6+x$
Simplify.
$2x=y+6$
Divide each side by $2$.
$\frac{2x}{2}=\frac{y+6}{2}$
Simplify.
$x=\frac{y+6}{2}$
Hence, the given solution is incomplete.
