x in (-oo:+oo)
(4*x+2)/8-((2*x-3)/9) = -2 // + 2
(4*x+2)/8-((2*x-3)/9)+2 = 0
(4*x+2)/8+(-1*(2*x-3))/9+2 = 0
(9*(4*x+2))/(8*9)+(-1*8*(2*x-3))/(8*9)+(2*8*9)/(8*9) = 0
9*(4*x+2)-1*8*(2*x-3)+2*8*9 = 0
20*x+42+144 = 0
20*x+186 = 0
(20*x+186)/(8*9) = 0
(20*x+186)/(8*9) = 0 // * 8*9
20*x+186 = 0
20*x+186 = 0 // - 186
20*x = -186 // : 20
x = -186/20
x = -93/10
x = -93/10
