Question
Answer
$$x-a-y+y=-a+x$$
Explanation
| $$ \begin{aligned}x-a-y+y& \xlongequal{ }x-a -\cancel{y}+ \cancel{y} \xlongequal{ } \\[1 em] & \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}-a+x\end{aligned} $$ | |
| ① | Combine like terms: $$ x-a \, \color{blue}{ -\cancel{y}} \,+ \, \color{blue}{ \cancel{y}} \, = -a+x $$ |
