To solve the equation \( 2x = 20 \), we first divide both sides by 2:
\[ x = \frac{20}{2} = 10 \]
The solution set containing the value that makes the equation true is expressed in set notation as:
\[ {10} \]
Use set notation to express the value(s) that make the equation 2x=20 true. Enter your response using set notation.(1 point)
