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