| $$ \begin{aligned}8(x+5)+2(3x-6)& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}8x+40+6x-12 \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle2}{\textcircled {2}} } }}}14x+28\end{aligned} $$ | |
| ① | Multiply $ \color{blue}{8} $ by $ \left( x+5\right) $ $$ \color{blue}{8} \cdot \left( x+5\right) = 8x+40 $$Multiply $ \color{blue}{2} $ by $ \left( 3x-6\right) $ $$ \color{blue}{2} \cdot \left( 3x-6\right) = 6x-12 $$ |
| ② | Combine like terms: $$ \color{blue}{8x} + \color{red}{40} + \color{blue}{6x} \color{red}{-12} = \color{blue}{14x} + \color{red}{28} $$ |
