| $$ \begin{aligned}4x\cdot2y+3y\cdot(2-x)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}8xy+6y-3xy \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}5xy+6y\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{3y} $ by $ \left( 2-x\right) $ $$ \color{blue}{3y} \cdot \left( 2-x\right) = 6y-3xy $$ |
| ② | Combine like terms: $$ \color{blue}{8xy} +6y \color{blue}{-3xy} = \color{blue}{5xy} +6y $$ |
