| ① | Remove the parentheses by changing the sign of each term within them. $$ - \left(y-x \right) = -y+x $$ |
| ② | Multiply $ \color{blue}{6} $ by $ \left( 5x+7\right) $ $$ \color{blue}{6} \cdot \left( 5x+7\right) = 30x+42 $$ |
| ③ | Combine like terms: $$ -y+ \color{blue}{x} + \color{blue}{30x} +42 = \color{blue}{31x} -y+42 $$ |
