Use set notation to express the value(s) that make the equation 2x=20%0D%0A2%0D%0A𝑥%0D%0A=%0D%0A20%0D%0A true. Enter your response using set notation.

1 answer

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

  1. Divide both sides by 2:

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

  1. Simplify:

\[ x = 10 \]

Now, using set notation to express the solution, we write:

\[ { 10 } \]

Thus, the set notation for the value that makes the equation true is \( { 10 } \).
