To go from the equation \( 2x + 7y = 14 \) to the equivalent equation \( 4x + 14y = 28 \), you need to multiply the entire equation by 2.

Here's the step-by-step process:

1. Start with the original equation:
\[
2x + 7y = 14
\]

2. Multiply every term in the equation by 2:
\[
2(2x) + 2(7y) = 2(14)
\]

3. This results in:
\[
4x + 14y = 28
\]

Thus, the operation performed is multiplying the entire equation by 2.
