Can someone please show me (STEP BY STEP!!!!!!!!!) how to properly distribute the following:
2 + 1/7 [x  (x+6 / 7)  2]
This is what I have:
= 2 + 1/7 ( x x6/7 2)
= 2 + (x  x  6  2 / 49)
= (98 + x  x  6  2) / 49
= 90/49
But the answer is:
6x + 78 / 49

I believe you meant to type:
2 + 1/7 [x  (x+6)/7  2]
= 2 + 1/7[(7x  x  6  14)/7]
= 2 + 1/7[(6x  20)/7]
= 2 + [(6x  20)/49]
= 98/49 + (6x  20)/49
= (98 + 6x  20)/49
= (6x + 78)/49
watch how you place your brackets, it is extremely important

= 2 + 1/7[(7x  x  6  14)/7]
Can you explain how you distributed this part thoroughly?
