-$$ a - x = b + x \qaud (a \in \Bbb{N}, b \in \Bbb{N}, a>b) $$
+$ a - x = b + x \quad (a \in \Bbb{N}, b \in \Bbb{N}, a>b) $
 
 ## 解法1
 
-$ \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} $

+\begin{aligned}
+2x &= a - b  &(移项并交换等式两侧) \\\\
+ 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`
-
 $ x = \frac{a+b}{2} - b $
