2a + 3/7 + 2a + 5/14 = 4a + 3/7 + 5/14
= (4a*14)/14 + (3*2)/14 + 5/14 (taking lcm)
= (56a + 6 + 5)/14
= (56a + 11)/14

2a+3/7+2a+5/14

= (2a+3)/7 + (2a+5)/14

= (2(2a+3) + (2a+5)) /14

= (6a+11)/14

(2a + 3)/7 + (2a + 5)/14
= [2(2a + 3)]/[2(7)] + (2a + 15)/14
= [2(2a) + 2(3)]/14 + (2a + 15)/14
= [4a + 6]/14 + (2a + 15)/14
= (4a + 6 + 2a + 15)/14
= (6a + 21)/14
