Explanation
| $$ \begin{aligned}9x-5y+3x+2y-7& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}12x-3y-7\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{9x} \color{red}{-5y} + \color{blue}{3x} + \color{red}{2y} -7 = \color{blue}{12x} \color{red}{-3y} -7 $$ |
