Hi
Solving for x
{{{x+1 = 2/x }}}   |Multiplying thru x
  x^2 + x = 2
   x^2 + x -2 = 0   |Setting Polynomial to zero     
factoring
 (x+2)(x-1)= 0  Note:SUM of the inner product(2x) and the outer product(-x) =x   
   (x+2)=0   x = -2
   (x-1)= 0  x = 1   

CHECKING our Answer(s)***
  -1 = 2/-2 = -1
  2 = 2/1 = 2
