let's solve :

$\hookrightarrow \: {y}^{2} + 14y - 5x + 64 = 0$

$\hookrightarrow \: 5x = {y }^{2} + 14y + 64$

$\hookrightarrow \: 5x = {y}^{2} + 14y + 49 + 15$

$\hookrightarrow \: 5x = (y + 7) {}^{2} + 15$

$\hookrightarrow \: x = \dfrac{(y + 7) {}^{2} + 15 }{5}$

$\hookrightarrow \: x = \dfrac{1}{5} (y + 7) {}^{2} + 3$

therefore, the correct option is B
