(6*x+1)/4 = (-2*x-4)/3 // - (-2*x-4)/3
(6*x+1)/4-((-2*x-4)/3) = 0
(6*x+1)/4+(-1*(-2*x-4))/3 = 0
(3*(6*x+1))/(3*4)+(-1*4*(-2*x-4))/(3*4) = 0
3*(6*x+1)-1*4*(-2*x-4) = 0
26*x+19 = 0
(26*x+19)/(3*4) = 0
(26*x+19)/(3*4) = 0 // * 3*4
26*x+19 = 0
26*x+19 = 0 // - 19
26*x = -19 // : 26
x = -19/26
x = -19/26
