Question

use set notation to express the value that makes the equation 2X equals 20 true

Answer 1

To express the value that makes the equation \( 2X = 20 \) true using set notation, we first solve the equation for \( X \).

1. Divide both sides by 2:
\[
X = \frac{20}{2} = 10
\]

Now, we can express this solution in set notation. The solution set containing the value for \( X \) can be expressed as:

\[
\{ 10 \}
\]

So, the solution in set notation is \( \{ 10 \} \).
