Assuming \( [x;y]\in\mathbb{R}\times\mathbb{R} \), solve the equation
\[ x-y-\frac{x-y}2=\frac{x-y}3 \]
Decide which of the answers below does not express the set of roots.
\( \left\{[x;y],x\in\mathbb{R},y\in\mathbb{R}\right\} \)
\( \left\{[x;x],x\in\mathbb{R}\right\} \)
\( \left\{[y;y],y\in\mathbb{R}\right\} \)
\( \left\{[t;t],t\in\mathbb{R}\right\} \)
