%282%2F3%29%286x+%2B+15%29+-+%283%2F7%29%2821x+-+14%29+=+19
Multiply both side by 3%2A7,
14%286x%2B15%29-9%2821x-14%29=399
84x%2B210-189x%2B126=399
-105x%2B336=399
-105x=63
x=-63%2F105

2/3(6x + 15) - 3/7(21x - 14) = 19
------------------
Multiply thru by 21 to get:
14(6x+15) - 9(21x-14) = 21*19
----
84x + 210 - 189x + 126 = 399
----------------------------
-105x + 336 = 399
====
-105x = 63
x = -63/105
