x in (-oo:+oo)
15*x-((6*x-18)/12) = 9/2 // - 9/2
15*x-((6*x-18)/12)-(9/2) = 0
15*x-((6*x-18)/12)-9/2 = 0
(-1*(6*x-18))/12+15*x-9/2 = 0
(-1*2*(6*x-18))/(2*12)+(2*12*15*x)/(2*12)+(-9*12)/(2*12) = 0
2*12*15*x-1*2*(6*x-18)-9*12 = 0
348*x-108+36 = 0
348*x-72 = 0
(348*x-72)/(2*12) = 0
(348*x-72)/(2*12) = 0 // * 2*12
348*x-72 = 0
348*x-72 = 0 // + 72
348*x = 72 // : 348
x = 72/348
x = 6/29
x = 6/29
