Based on your description, it seems like you want to create an equation representing a function that takes an input \( x \) and produces an output. The function is defined as:
\[ y = 2x + 3 \]
In this equation:
- \( y \) represents the output.
- \( x \) represents the input.
- The function multiplies the input \( x \) by 2 and then adds 3 to produce the output \( y \).
