Und nun noch einmal :

      x + 8 = 14x                   /  -14x

-13x + 8 = 0                       /   -8

      -13x  =  -8                   /    : (-13)

            x =  8/13         ;     $${\mathtt{x}} = {\frac{{\mathtt{8}}}{{\mathtt{13}}}}$$     ;    $${\mathtt{x}} = {\frac{{\mathtt{8}}}{{\mathtt{13}}}} \Rightarrow {\mathtt{x}} = {\mathtt{0.615\: \!384\: \!615\: \!384\: \!615\: \!4}}$$

 x = $$0,\overline{615384}$$

x + 8 = 14 x |-14x

-13x+8=0 |-8

-13x =-8 |:(-8)

x =8/13

yx=0,615384615…
