0.03-x = 0
0.03-x = 0
0.03-x = 0
0.03-x = 0 // - 0.03
-x = -0.03 // * -1
x = 0.03
x in (-oo:0.03) U (0.03:+oo)
x/(0.03-x) = 2.6 // - 2.6
x/(0.03-x)-2.6 = 0
x/(0.03-x)+(-2.6*(0.03-x))/(0.03-x) = 0
x-2.6*(0.03-x) = 0
3.6*x-0.078 = 0
(3.6*x-0.078)/(0.03-x) = 0
(3.6*x-0.078)/(0.03-x) = 0 // * 0.03-x
3.6*x-0.078 = 0
3.6*x-0.078 = 0 // + 0.078
3.6*x = 0.078 // : 3.6
x = 0.078/3.6
x = 0.02166667
x = 0.02166667
