Hi

%283x+%2B+6%29%2F8+=+6%2F%282x+%2B+4%29   | Cross Multiplying to solve

 (3x+6)(2x+4) = 48

  6x^2 + 24x + 24 = 48

  6x^2 + 24x - 24 = 0

   x^2 + 4x -4 = 0

x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+ 

x+=+%28-4+%2B-+sqrt%28+32%29%29%2F%282%29+ 

x+=+%28-4+%2B-+sqrt%28+16%2A2%29%29%2F%282%29+ 

 x = -2 ± 2√2
