x in (-oo:+oo)
(2*x-1)/3+(3*x+4)/4 = (7*(x-3))/10 // - (7*(x-3))/10
(2*x-1)/3+(3*x+4)/4-((7*(x-3))/10) = 0
(2*x-1)/3+(3*x+4)/4+(-7/10)*(x-3) = 0
(2*x-1)/3+(3*x+4)/4-7/10*(x-3) = 0
(4*(2*x-1))/(3*4)+(3*(3*x+4))/(3*4)+(-7/10*3*4*(x-3))/(3*4) = 0
4*(2*x-1)+3*(3*x+4)-7/10*3*4*(x-3) = 0
17*x-42/5*x+8+126/5 = 0
43/5*x+166/5 = 0
(43/5*x+166/5)/(3*4) = 0
(43/5*x+166/5)/(3*4) = 0 // * 3*4
43/5*x+166/5 = 0
43/5*x+166/5 = 0 // - 166/5
43/5*x = -166/5 // : 43/5
x = -166/5/43/5
x = -166/43
x = -166/43
