Missing \left or extra \right

\bar{x} = - 1 [5] \Rightarrow x + 1 = 5 k \Rightarrow x = 5 k - 1 w i t h k \in Z .

6 x \equiv 4 + 4 \times 5 = 24 (m o d 5)

x \equiv 4 (m o d 5)

6 x = 5 n + 4 = 5 (n - 4) + 24

x = \frac{5 (n - 4)}{6} + 4

w i t h n - 4 = 6 m

\Rightarrow x = 5 m + 4

i . e . x \equiv 4 (m o d 5)
