Explanation
| $$ \begin{aligned}7x^3-3+4+2x^3& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}9x^3+1\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{7x^3} \color{red}{-3} + \color{red}{4} + \color{blue}{2x^3} = \color{blue}{9x^3} + \color{red}{1} $$ |
