Answer:

A

Step-by-step explanation:

(5x/9 + 1/6) + (3x/8 + 4/7) = 5x/ 9 + 3x/8 + 1/6 + 4/7           (add like terms)

= (5x*8/ 9*8) + ( 3x*9/8*9) + (1*7/6*7)  + (4*6/7*6)

                                                  {LCM of 8,9 is 72 and LCM of 6,7 is 42}

= 40x/72 +  27x/72  + 7/42 + 24/42

= (40x + 27x)72 + (7 +24)/42

= 67x/72 + 31/42

= 67x/72 + 31/42
