-%28x%2B1%29+=+2%283x-1%29
-x-1+=+2%283x-1%29 ... distribute the negative sign on the left
-x-1+=+6x-2 ... distribute the 2 on the right
-1+=+7x-2 ... add x to both sides
1+=+7x ... add 2 to both sides
1%2F7+=+x ... divide both sides by 7

Thus, x = 1/7. To check, we substitute 1/7 in for x in the original equality, and see if it holds true.
-%281%2F7%2B1%29+=+2%283%281%2F7%29-1%29
-%281%2F7%2B7%2F7%29+=+2%283%281%2F7%29-1%29
-8%2F7+=+2%283%281%2F7%29-1%29
-8%2F7+=+2%283%2F7-1%29
-8%2F7+=+2%283%2F7-7%2F7%29
-8%2F7+=+2%28-4%2F7%29
-8%2F7+=+-8%2F7 ... yes!
