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

1 answer

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

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

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

In set notation, this can be expressed as:

\[ {10} \]

Thus, the answer is \( {10} \).
