To solve the equation \( x5 = 20 \), we first rewrite it for clarity. It's likely that the equation should be interpreted as:
\[ x \cdot 5 = 20 \]
To isolate \( x \), divide both sides of the equation by 5:
\[ x = \frac{20}{5} \]
Now, calculate the right-hand side:
\[ x = 4 \]
So the solution is:
\[ x = 4 \]
