| $$ \begin{aligned}-5+5(-4x+3)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-5-20x+15 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}-20x+10\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{5} $ by $ \left( -4x+3\right) $ $$ \color{blue}{5} \cdot \left( -4x+3\right) = -20x+15 $$ |
| ② | Combine like terms: $$ \color{blue}{-5} -20x+ \color{blue}{15} = -20x+ \color{blue}{10} $$ |
