v = 9.5

Step-by-step explanation:

$\\ \tt \frac{4}{5} (v - 7) = 2$

$\\ \tt \mapsto \frac{4(v - 7)}{5} = 2$

$\\ \tt\mapsto \frac{4v - 28}{5} = 2$

$\\ \tt \mapsto4v - 28 = 2 \times 5$

$\\ \tt \mapsto4v - 28 = 10$

$\\ \tt \mapsto4v = 10 + 28$

$\\ \tt \mapsto \: v = \frac{38}{4}$

$\\ \tt \mapsto \: v = 9\frac{2}{4} \: or \: 9.5$
