To solve the equation \(2x = 20\), we first isolate \(x\) by dividing both sides of the equation by 2:

\[
x = \frac{20}{2} = 10
\]

The value that satisfies the equation is \(x = 10\).

Using set notation to express this solution, we can write:

\[
\{ x \in \mathbb{R} \mid x = 10 \}
\]

Alternatively, we can use simpler set notation:

\[
\{ 10 \}
\]

This represents the value(s) that make the equation true.
