 $ a - x = b + x \space (a \in \Bbb{N}, b \in \Bbb{N}, a>b) $
 
 ## 解法1
 
-$ 2x = a - b \space (移项并交换等式两侧)$
-
-$ x=\frac{a-b}{2} \space (等式两侧同除以2)$
+$ \begin{aligned} 2x &= a - b  &(移项并交换等式两侧) \newline x &=\frac{a-b}{2}  &(等式两侧同除以2) \end{aligned} $
 
 ## 解法2
 
-$x=\frac{a+b}{2}-b$
+$ x = \frac{a+b}{2} - b $
