| ① | Multiply $ \color{blue}{5} $ by $ \left( 3x+2\right) $ $$ \color{blue}{5} \cdot \left( 3x+2\right) = 15x+10 $$ |
| ② | Combine like terms: $$ \color{blue}{4} +15x+ \color{blue}{10} = 15x+ \color{blue}{14} $$ |
| ③ | Combine like terms: $$ \color{blue}{15x} +14 \color{blue}{-2x} = \color{blue}{13x} +14 $$ |
