To go from the equation \( 2x + 7y = 14 \) to the equivalent equation \( 4x + 14y = 28 \), you need to multiply the entire equation by \( 2 \).
So, you should multiply the equation \( 2x + 7y = 14 \) by \( 2 \):
\[
2(2x + 7y) = 2(14)
\]
This results in:
\[
4x + 14y = 28
\]
Therefore, the answer is that you should multiply by **2**.
