[tex]\mathfrak{\huge{Answer:-}} \\ \bold{\frac{2a + 4}{7} + \frac{a - 3}{2} = 3} \\ \frac{2(2a + 4) + 7(a - 3)}{14} = 3 \\ \frac{4a + 8 + 7a - 21}{14} = 3 \\ \frac{4a + 7a + 8 - 21}{14} = 3 \\ \frac{11a - 13}{14} = 3 \\ 11a - 13 = 3 \times 14 \\ 11a - 13 = 42 \\ 11a = 42 + 13 \\ 11a = 55 \\ a = \frac{55}{11} \\ \boxed{\boxed{\bold{\large{a = 5}}}}[/tex]
