Use set notation to express the value(s) that make the equation 2x = 20 true. Enter your response using set notation.

To solve the equation \( 2x = 20 \), we can divide both sides by 2:

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

The value that makes the equation true is \( x = 10 \). In set notation, we express this as:

\[
\{10\}
\]
