The equation provided in the image is:

$3x + 2 = y$

We are given that $x = 4$. Now, we can substitute this value of $x$ into the equation to solve for $y$:

$y = 3(4) + 2 = 12 + 2 = 14$

Thus, $y = 14$.

The correct answer is 14.

Would you like any further details or have any questions? Here are some related questions to consider:

1. What happens if $x = 5$ in the equation $3x + 2 = y$?
2. How would the equation change if it was $3x - 2 = y$?
3. Can you solve for $x$ if $y = 20$?
4. How would the graph of this equation look like?
5. What is the slope of the equation $y = 3x + 2$?

Tip: Always substitute known values into the equation before simplifying.
