Hello Friend.

Here is your answer below,,

$\frac{5x}{3} - 4 = \frac{2x}{5} \\ = > \frac{5x - 12}{3} = \frac{2x}{5} \\ = > 5(5x - 12) = 2x \times 3 \\ = > 25x - 60 = 6x \\ = > 25x - 6x = 60 \\ = > 19x = 60 \\ = > x = \frac{60}{19} \\ \\ now \: going \: to \: you \: question \: of \: numerical \\ \: value \: of \: \: (2x - 7) \\ = > 2x - 7 \\ = > 2 \times \frac{60}{19} - 7 \\ = > \frac{120}{19} - 7 \\ = > \frac{120 - 133}{19} \\ = > - \frac{13}{19} \: \: \: \: \: \: answer.$
