2.43-x = 0
2.43-x = 0
2.43-x = 0
2.43-x = 0 // - 2.43
-x = -2.43 // * -1
x = 2.43
x in (-oo:2.43) U (2.43:+oo)
9.4 = x/(2.43-x) // - x/(2.43-x)
9.4-(x/(2.43-x)) = 0
(-1*x)/(2.43-x)+9.4 = 0
(-1*x)/(2.43-x)+(9.4*(2.43-x))/(2.43-x) = 0
9.4*(2.43-x)-1*x = 0
22.842-10.4*x = 0
(22.842-10.4*x)/(2.43-x) = 0
(22.842-10.4*x)/(2.43-x) = 0 // * 2.43-x
22.842-10.4*x = 0
22.842-10.4*x = 0 // - 22.842
-10.4*x = -22.842 // : -10.4
x = -22.842/(-10.4)
x = 2.19634615
x = 2.19634615
