3x/x+1 + 6/2x =7/x
---------------
Eliminate fractions by multiplying by the denominators.
3x/x+1 + 6/2x =7/x
Multiply by x
3x%5E2%2F%28x%2B1%29+%2B+3+=+7
3x%5E2%2F%28x%2B1%29+=+4
Multiply by (x+1)
3x%5E2+=+4%2A%28x%2B1%29
3x%5E2+-+4x+-+4+=+0
(3x-1)*(x-1) = 0
x = 1/3, x = 1
-----------
The LCD has nothing to do with it.
