Notes

Reverse the reaction: $\displaystyle K'=\frac{1}{K}$.
Multiply coefficients by $n$: $K'=K^n$.
Add reactions: multiply their $K$ values.

Practice

$K=4$ for $A\rightleftharpoons B$. For $B\rightleftharpoons A$:

$K=4$ for $A\rightleftharpoons B$. For $2A\rightleftharpoons 2B$:

Two reactions add together with $K_1=3$ and $K_2=5$. Overall $K$:
