| ① | Combine like terms: $$ \color{blue}{6x} +2 \color{blue}{-5x} = \color{blue}{x} +2 $$ |
| ② | Remove the parentheses by changing the sign of each term within them. $$ - \left( x+2 \right) = -x-2 $$ |
| ③ | Combine like terms: $$ \color{blue}{1} + \color{red}{2x} \color{red}{-x} \color{blue}{-2} = \color{red}{x} \color{blue}{-1} $$ |
