x in (-oo:+oo)
(31/2)*(x+1)+(1/3)*(x+2) = 3-((1/4)*(x+3)) // - 3-((1/4)*(x+3))
(31/2)*(x+1)+(1/3)*(x+2)+(1/4)*(x+3)-3 = 0
31/2*(x+1)+1/3*(x+2)+1/4*(x+3)-3 = 0
31/2*(x+1)+1/3*(x+2)+1/4*(x+3)-3 = 0
95/6*x+1/4*x-3+3/4+97/6 = 0
193/12*x-3+203/12 = 0
193/12*x+167/12 = 0
193/12*x+167/12 = 0
193/12*x+167/12 = 0 // - 167/12
193/12*x = -167/12 // : 193/12
x = -167/12/193/12
x = -167/193
x = -167/193
