Solution for (1/x)+(1/x+2)=(1/7) equation:


D( x )

x = 0

x = 0

x = 0

x in (-oo:0) U (0:+oo)

1/x+1/x+2 = 1/7 // - 1/7

1/x+1/x-(1/7)+2 = 0

1/x+1/x-1/7+2 = 0

2*x^-1 = -13/7 // : 2

x^-1 = -13/14

-1 < 0

1/(x^1) = -13/14 // * x^1

1 = -13/14*x^1 // : -13/14

-14/13 = x^1

x = -14/13

x = -14/13
