Answer
$$x\cdot3+x\cdot2y-xy\cdot2-y\cdot3=3x-3y$$
Explanation
| $$ \begin{aligned}x\cdot3+x\cdot2y-xy\cdot2-y\cdot3& \xlongequal{ }3x+ \cancel{2xy} -\cancel{2xy}-3y \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}3x-3y\end{aligned} $$ | |
| ① | Combine like terms: $$ 3x+ \, \color{blue}{ \cancel{2xy}} \, \, \color{blue}{ -\cancel{2xy}} \,-3y = 3x-3y $$ |
