| ① | $$ 3 x \cdot 2 = 6 x $$$$ 4 x \cdot 2 = 8 x $$ |
| ② | Combine like terms: $$ \color{blue}{6x} \color{blue}{-8x} +6 = \color{blue}{-2x} +6 $$Combine like terms: $$ 2 \color{blue}{-2x} + \color{blue}{8x} = \color{blue}{6x} +2 $$ |
| ③ | Combine like terms: $$ \color{blue}{-2x} + \color{red}{6} + \color{blue}{6x} + \color{red}{2} = \color{blue}{4x} + \color{red}{8} $$ |
