Question
Answer
$$3g+5h+2i-5g+2h-2i=-2g+7h$$
Explanation
| $$ \begin{aligned}3g+5h+2i-5g+2h-2i& \xlongequal{ }3g+5h+ \cancel{2i}-5g+2h -\cancel{2i} \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-2g+7h\end{aligned} $$ | |
| ① | Combine like terms: $$ \color{blue}{3g} + \color{red}{5h} + \, \color{green}{ \cancel{2i}} \, \color{blue}{-5g} + \color{red}{2h} \, \color{green}{ -\cancel{2i}} \, = \color{blue}{-2g} + \color{red}{7h} $$ |
