Answer choice $B$

Work Step by Step

First, you need to make sure there is a constant on one side, and the rest of the terms on the other side. You need to subtract $\frac{2}{7}x$ from each side. $-\frac{2}{7}x + y = -4$ The coefficient of $x$ must be a positive integer. Multiply both sides by $-7$. $\boxed{2x - 7y = 28}$ The answer is $\boxed{B}$
