| ① | Multiply $ \color{blue}{3} $ by $ \left( x+4\right) $ $$ \color{blue}{3} \cdot \left( x+4\right) = 3x+12 $$Multiply $ \color{blue}{2} $ by $ \left( x-3\right) $ $$ \color{blue}{2} \cdot \left( x-3\right) = 2x-6 $$ |
| ② | Combine like terms: $$ \color{blue}{3x} + \color{red}{12} + \color{blue}{2x} \color{red}{-6} = \color{blue}{5x} + \color{red}{6} $$ |
