​

Answer 1

Answer:

$\: \: \: \: \: \: \: \frac{3a - 2}{7} - \frac{ a- 2}{4} = 2 \\ = > \frac{4(3a - 2) - 7(a - 2)}{28} = 2 \\ = > \frac{12a - 8 - 7a + 14}{28} = 2 \\ = > \frac{5a + 6}{28} = 2 \\ = > 5a + 6 = 28 \times 2 \\ = > 5a + 6 = 56 \\ = > 5a = 56 - 6 \\ = > 5a = 50 \\ = > a = \frac{50}{5} \\ = > a = 10$
