| ① | Multiply $ \color{blue}{3} $ by $ \left( x-2a\right) $ $$ \color{blue}{3} \cdot \left( x-2a\right) = 3x-6a $$Multiply $ \color{blue}{4} $ by $ \left( 2+2x\right) $ $$ \color{blue}{4} \cdot \left( 2+2x\right) = 8+8x $$ |
| ② | Combine like terms: $$ \color{blue}{3x} -6a+8+ \color{blue}{8x} = -6a+ \color{blue}{11x} +8 $$ |
